Hungary accused Ukraine of an "outrageous and unacceptable" attack that disabled a Russian oil pipeline supplying the NATO ally—and fired a warning to Kyiv about its reliance on Hungarian electricity supplies. Newsweek has contacted the Ukrainian foreign ministry for comment.

Ahead of the summit with Ukrainian President Volodymyr Zelenskyy and other European leaders in Washington on Monday, President Donald Trump said Ukraine should give up efforts for NATO membership and Russian-annexed Crimea.

Donald Trump said on his social media handle that Zelenskyy can end the war with Russia almost immediately, if he wants to, or he can continue to fight.
