Ukraine-Russia war latest: Kremlin ‘won’t accept ultimatum’ from Europe as Putin warns of major retaliation 

The Kremlin has said that Russia is open to dialogue with Europe but “won’t accept ultimatums” in a statement on Friday.

Russian strikes killed at least two people and wounded ⁠two others in the northeastern Ukrainian ⁠region ​of Sumy after Moscow threatened escalation for Ukraine’s biggest assault so far.

Another nine people, ‌including four children, suffered injuries in Kharkiv, which was attacked with Russian guided aerial bombs.

Ukraine on Friday morning claimed that a crew member of a Panama-flagged ship was killed in a Russian drone attack in the Black Sea waters. Oleksiy Kuleba said that another vessel under the Saint Kitts and Nevis flag was ‌also hit.

Russian foreign minister Sergei Lavrov previously warned of “massive coordinated strikes on a regular basis” in response to Ukraine’s attack on a Moscow oil refinery for the second time this week.

Ukraine earlier launched a heavy drone strike on Russia in retaliation for damage done to a historic monastery in Kyiv this week. Hundreds of drones targeted Moscow overnight, hitting the Russian capital’s oil refinery for the ⁠second time this week, in one of the biggest aerial assaults on Russia of the war so far.
