A Russian attack that killed at least 17 people including three children in Ukraine are Moscow’s “thanks for the lifting on sanctions on diesel exports,” Ukrainian President Volodymyr Zelenskyy said Saturday.

A series of strikes on the south-eastern city of Zaporizhzhia also injured at least 18 people, including three children, Ukraine’s state emergency services said on Saturday afternoon.

“People continue to be searched for under the rubble of destroyed houses. Rescue operations continue,” said Mykhailo Semikin, acting head of Zaporizhzhia regional military administration in a Telegram post.

“Today, Russia expressed its thanks for the lifting of sanctions on diesel exports by dropping five glide bombs on residential buildings in Zaporizhzhia,” Zelenskyy said on X.

The strikes took place just one day after U.S. President Donald Trump announced he would temporarily lift sanctions on Russian diesel in a bid to bring soaring prices down.

Ukrainian officials were meeting on the same day with European and U.S. officials in Miami in a fresh diplomatic push to end the conflict between Russia and Ukraine.

Zelenskyy criticized the deal on Friday and accused Trump of using the peace talks as a “smokescreen” while pursuing a deal with the Kremlin.

Even though the talks were supposed to last two days, the Ukrainian team decided to return home earlier then planned “because they managed to talk everything through earlier,” a senior official familiar with the matter told POLITICO. Ukraine will continue to bomb Russian oil refineries despite US-Russia deals, the official added.

The Ukrainian armed forces said Saturday they struck a major oil facility in Russia’s Samara region overnight.

Zelenskyy is currently busy coordinating with Europeans and preparing several high-level meetings, the official said. He spoke on Saturday with leaders of France, Norway and Finland.

“Russian strikes killed over 80 Ukrainian civilians in two days. Moreover, it has stepped up its hybrid attacks against Europe, both EU Member States and NATO Allies,” Kaja Kallas, the EU’s foreign policy chief, said Saturday. “Suspending sanctions on Russian diesel provides Moscow with more revenues to wage war.”

“On Monday, EU Foreign Ministers intend to approve the biggest set of sanctions listings targeting Russia’s war machine since the start of the war,” Kallas added.
