Ukraine says its ‘lockdown’ strategy is working as it disrupts Russian supply lines.

KYIV, June 12 (Reuters) - Ukraine is seeking an additional $20 billion in military funding from its allies to cement what it sees as its current battlefield advantage over Russia, a Ukrainian defence source said on Friday.

Ukrainian President Volodymyr Zelenskyy said Ukraine has received intelligence indicating Russia will launch an assault involving drones and missiles.

The Ukrainian Air Force on Friday warned the public of a likely new launch of the Russian Oreshnik medium-range ballistic missile, a potentially devastating weapon able to carry multiple warheads that Moscow has deployed against the neighbouring country three times in the past.

At least three people were killed near Moscow after Ukraine targeted Russia with more than 500 drones overnight, Russian state news agency TASS reported Sunday, citing local and military officials.

Russian missile, drone strikes kill at least 22 people across Ukraine, authorities say, after President Zelenskyy warned Moscow was planning a "massive new strike."

Russia on Monday urged foreign citizens, including members of diplomatic missions, to leave the Ukrainian capital as quickly as possible and told residents to steer clear of military and government facilities.

Russia’s air attacks have grown in sheer volume in recent months, hammering Ukraine with more drones and high-speed missiles than ever before, as Moscow’s forces struggle to make meaningful progress on the ground.

Russian forces launched a massive aerial attack on Kyiv and other Ukrainian cities, and officials say at least 22 civilians were killed and 138 were wounded.

A series of long-range Ukrainian attacks hit targets deep inside Russia on Wednesday, part of Kyiv’s efforts to raise the costs of the war for the Kremlin by striking energy facilities and military industries.
