Moscow has said the US bears equal responsibility for a strike on Crimea that killed at least four, including two children. Meanwhile, the EU has adopted a new package of sanctions targeting Russia. 

Russia’s Foreign Ministry summoned US Ambassador Lynne Tracy on Monday after Sunday’s missile strike on Crimea in which four people were killed, including two children.

Tracy was told by the Foreign Ministry that Washington “bears equal responsibility with the Kyiv regime for this atrocity,” and warned there would be consequences.

Kremlin spokesman Dmitry Peskov called the strike on Sevastopol “barbaric” and accused Washington of “killing Russian children.”

“The involvement of the United States, the direct involvement, as a result of which Russian civilians are killed, cannot be without consequences,” Peskov told reporters. “Time will tell what these will be.”

Russia said Sunday’s strikes on Sevastopol had been carried out with US-supplied ATACMS missiles, four of which were intercepted.

Russia’s Foreign Ministry said the explosion of the fragmentation warhead of the fifth missile caused the casualties.

Russia occupied the Ukrainian province of Crimea in 2014 and subsequently annexed it in an illegal move that has not been recognized by the international community.

Andriy Yermak, the head of the Ukrainian president’s office, wrote on Telegram on Monday: “Crimea is Ukraine.”

“Russia must leave the peninsula. Their army and military objects there must cease to exist.”
