KYIV — Russia caught the Ukrainian capital off guard with its latest attack, hitting the country with over 100 drones and five ballistic missiles, President Volodymyr Zelenskyy said Tuesday.

“Intelligence on Russian ballistic missile launches helps save lives, and this is one of the most critical issues. This is precisely what helps prevent people from being killed — when there is an early warning about ballistic missiles,” Zelenskyy said.

He added: “Regarding this strike, unfortunately, there was no warning from partners.”

Kyiv usually receives a tip-off about impending Russian missiles via the Battlespace Command and Control Center system, which is operated and controlled by the United States’ military and NATO members, among others.

However, Ukrainian Foreign Minister Andrii Sybiha said at the Warsaw Security Forum Tuesday that intelligence sharing through the platform is ongoing.

“They [Americans] told Ukrainians no warning happened because of bad weather conditions, which is seen as not an adequate reason in Kyiv. Thus many are getting increasingly worried this might not have been the case,” an official familiar with the matter told POLITICO on condition of anonymity.

The missile warning system has malfunctioned before. “At times this information doesn’t get through. This isn’t the first instance … If there were specific technical issues this time, I think the specialists will sort it out. And they will resolve this problem together with our partners,” Ukrainian Air Force spokesperson Yurii Ignat said Tuesday.

The U.S. reportedly threatened to cut intelligence sharing once again last week if Kyiv does not stop stricking Russian oil refineries. Zelenskyy did not publicly confirm the threat, but has backed down.

“Ukraine has not carried out strikes on Russian oil refineries or the energy sector in general for the two days since the American President announced an energy ceasefire. But Russia did not heed the American President,” Zelenskyy said, appealing to the U.S. to lead peace negotiations.

“The Russians have attacked both our energy facilities and our critical infrastructure, sending absolutely clear signals that they have no intention of refraining from strikes on Ukraine. Nineteen regions of our country have come under attack in these two days alone,” he added.

U.S. President Donald Trump claimed Monday that both Russia and Ukraine had agreed to an energy ceasefire because he said so — “and if it was violated, they both violated it.”

“Actually [Russian President Vladimir Putin] wants to make a deal, and we have to get Zelenskyy to want to make a deal,” Trump said.

During a press briefing on Tuesday, Katie Zacharia, the president’s new press secretary, demurred when asked if the U.S. has stopped sharing intel with Ukraine.

“I’ll have to get back to you on that,” she said.

Speaking to reporters at the White House later on Tuesday, President Donald Trump said the U.S. has not stopped sharing intel with Ukraine.

“But we are really helping them get to a final answer,” Trump said. “We are helping them, and we are sharing intel. We want the war to end.”

He reiterated that he is helping to broker a deal between Putin and Zelenskyy. “There is a lot of hatred there between the two of them. They both want it to end, they don’t know how to get there. We’re gonna get them there,” he said.

Russia has not yet commented on the ballistic strikes, but issued a general statement saying it had struck military and weapons production facilities across Ukraine.

However, Russian Foreign Minister Sergei Lavrov said Monday that Zelenskyy did not deserve a pause in fighting in response to the energy ceasefire: “I don’t think that he deserves a break. I don’t think that we will buy assurances and promises again,” he said.

LONDON — Britain’s spies will have a leading role in Britain’s preparation for AI threats, the head of MI5 announced on Tuesday, after warning the technology could enable terrorists to access bioweapons.

Ken McCallum, director general of the U.K.’s domestic intelligence agency has established the AI Threat Assessment Centre to help determine how the government views potential threats.

Giving his annual threat update from MI5 headquarters in London, McCallum said: “Human history has given us no experience of facing an actor which is smarter than we are, is capable of outthinking us.”

He stressed the “real” risks of AI, saying MI5 has caught terrorists seeking to use AI to “improve their reconnaissance and attack methodologies,” in addition to the danger of AI-enabled drones.

Though it has not yet been “realized,” he said he attaches “the greatest weight” to AI’s potential to “change the stakes on existing or even new bioweapons.”

He said “low-capability” terrorists may get a “capability” uplift if the safety guardrails in AI models don’t work as intended. 

He added that for a long time “many terrorists would dearly love” access to chemical, biological or radiological weapons, but that it has been hard for them to achieve.

“One risk is that AI could enable dangerous knowledge to get into the hands of people who […] didn’t have that knowledge.”

McCallum added that “sober attention” must be given to the risk that “AI could generate novel pathogens not previously seen.” He noted that the government is taking “additional steps” on bioweapons. 

One thing that “does trouble me”, McCallum said, is the pace at which the world is evolving. He noted that the “weird bits inside MI5” that focus on how Britain’s adversaries will act in five years from now are seeing those timelines shortening due to AI.

He said it is now his responsibility to “drag my organization forwards at a faster pace than human beings generally want to be dragged.”

Sifting threats from hype

The new threat assessment centre, known as AITAC, will bring together expertise from bodies including Britain’s AI Security Institute, National Crime Agency, and the National Cyber Security Centre to “separate the bluster from the realities” of AI’s threat to the British public.

This is the third center of its kind MI5 has set up, after creating similar units dedicated to analyzing terrorism and state threats.

Asked how the agency would work, McCallum said it would look at emerging trends and how the U.K. can best think about and prioritize the various manifestations of AI threats. 

Though the government, rather than AITAC, will decide the response to AI, McCallum said it was partly set up to avoid “competitive analysis, slightly conflicting and confusing messages that otherwise might exist, where you have different departments offering their own opinion” on the issue.

He said that it would enable everyone to have “a single version of the truth, a single understanding, a single lexicon, typography.”

McCallum also said MI5 will now give national resilience — such as protecting critical infrastructure, countering cognitive warfare, and addressing technology threats — “front-rank mission status” alongside its twin roles of countering state threats and terrorism.

He noted that MI5 is now devoting more resources to countering state threats than it was during the Cold War, noting an uptick in anti-immigration cases tipping into terrorist intent, while Iran has shifted its ambitions to hit harder targets such as military sites.

WARSAW — European leaders are preparing to demand tougher sanctions on Russia at a summit on Thursday, putting them at odds with Donald Trump just days after the U.S. president struck a deal with Vladimir Putin to ease restrictions on Russian diesel exports.

The leaders plan to call for further sanctions and measures targeting Moscow’s oil revenues at the European Council, according to a recent draft joint statement obtained by POLITICO, as EU governments reject Trump’s claim to have secured an energy ceasefire between Russia and Ukraine.

The disagreement exposes a widening divide over how to bring Moscow to the negotiating table. While Trump is seeking to bring down U.S. fuel prices by allowing more Russian diesel onto global markets, European leaders argue that restricting the Kremlin’s energy revenues remains essential to forcing Putin to end the war.

“Russia is not interested in deescalation, ceasing fire or peace,” Polish Prime Minister Donald Tusk told a security conference in Warsaw on Monday. “That is why I will go to Brussels to ask my partners to consider seriously increasing sanctions against Russia.”

German Chancellor Friedrich Merz also called for further restrictions, pointing to Moscow’s continued attacks on Ukraine’s energy infrastructure despite Trump’s announcement of a ceasefire.

“Russia will only negotiate in good faith under pressure,” Merz said Monday. “Following Moscow’s reckless attacks on Ukraine’s civilian energy supply, we must even tighten [sanctions] further.”

The push comes after EU foreign ministers on Monday approved the bloc’s largest-ever addition to its Russia sanctions list, targeting more than 1,600 individuals and entities. The European Commission is also preparing a 23rd package of sectoral sanctions, which Kyiv expects to be circulated to EU governments by the end of the year, according to a senior Ukrainian official who was, like others in this article, granted anonymity to speak frankly on the sensitive negotiations.

Other European countries are taking a similar position. Britain and Norway have also pledged to increase pressure on Moscow.

“It’s important to sanction Russia not to finance the war,” Norwegian Defense Minister Tore O. Sandvik told POLITICO, calling for loopholes in existing restrictions to be closed.

Trump’s election calculation

Behind closed doors, many European diplomats see Trump’s abrupt shift toward easing restrictions on Russian energy as driven primarily by domestic political concerns ahead of next month’s U.S. midterm elections.

That is the “broadly held view” among EU officials, according to one senior official.

The president is under mounting pressure over fuel prices, which have surged since the outbreak of the U.S.-Israeli war with Iran. Having promised during his 2024 campaign to bring gasoline prices below $2 a gallon, Trump now faces an electorate paying more than twice that amount, with Republicans at risk of losing control of Congress.

His agreement with Putin is intended to release an additional 4.8 million tons of Russian diesel onto global markets over the coming months, easing pressure on fuel supplies and prices.

But European and Ukrainian officials question whether the additional supply will make a meaningful difference, saying that the total volume promised amounts to only around 10 days of U.S. demand. They feel the deal risks undermining efforts to deprive Moscow of the revenues funding its invasion.

“The reality” is that the additional fuel will have a “minimal” impact on U.S. prices, the senior EU official said.

“This is about the midterms,” a second EU official said. “He said he would bring down prices, but then he decided to go to war with Iran.”

The officials also question whether Putin intends to honor Trump’s purported energy ceasefire. Russia has continued striking Ukrainian energy infrastructure since the announcement, while Kyiv says it was not consulted on the arrangement.

For now, most European officials are reluctant to criticize Trump publicly, despite any doubts about the agreement. The EU and Ukraine should maintain their position over the coming weeks, when the administration’s longer-term intentions toward Kyiv may become clearer, one diplomat said, adding that Trump might even change course again if Putin fails to deliver the promised diesel.

Pressure on Washington

The dispute has also revived European calls for Washington to enforce its own sanctions against Moscow.

Tusk urged Europe and the United States to act together to show Russia they were prepared to impose tougher measures, while EU foreign policy chief Kaja Kallas called on Washington to align its approach with Brussels.

Kallas pointed to sweeping Russia sanctions legislation championed by the late Republican Senator Lindsey Graham, which Trump signed into law last month but has yet to fully implement.

The legislation gives Washington additional tools to target Russia’s energy trade and those helping sustain its war effort. European officials want the administration to use them rather than loosen restrictions on Russian exports.

Some Republicans are also calling for tougher action.

“I think we need to be implementing the Russia sanctions bill,” Republican Representative Dan Crenshaw told the Warsaw conference.

The disagreement is raising wider questions in Europe about its dependence on Washington, particularly amid reports that U.S. officials have threatened to restrict Ukraine’s access to American weapons unless Kyiv stops attacking Russian oil refineries.

There is currently “no sign” Washington is following through on those threats, a NATO official told POLITICO, arguing that restricting sales would also hurt American weapons manufacturers.

“PURL is a good deal for the Americans,” the official said, referring to the NATO initiative under which European allies finance purchases of U.S. weapons for Ukraine.

European Defense Commissioner Andrius Kubilius, without directly addressing the reports, said Europe needed to take “primary responsibility” for its own defense more urgently as Washington reduces its military presence on the Continent.

The immediate test, however, comes on Thursday, when EU leaders will seek to maintain pressure on Moscow even as their most powerful ally moves in the opposite direction.
