Russia's Latest Strike on Ukrainian Army Headquarters: Over 500 Troops Killed.

Russia's defence ministry said assault troops were fighting in western parts of Bakhmut, the last part of the embattled Ukrainian city still held by Kyiv's forces. Germany rejected the possibility of delivering fighter jets to Ukraine, while Latvia announced the delivery of all Stinger anti-aircraft missiles still in its armed forces. NATO invited Ukrainian President Zelenskyy to its summit in July, and the UK imposed sanctions on a Russian judge and four others linked to the arrest of British-Russian Kremlin critic Vladimir Kara-Murza. Russia said it would not approve any new vessels for the safe Black Sea export of Ukraine grain unless their operators guarantee the transits will be done by May 18.
