WASHINGTON, April 21 (Reuters) - U.S. President Joe Biden pledged $800 million in more weaponry for Ukraine on Thursday and said he would ask Congress for more money to help bolster support for the Ukrainian military as it faces a fresh onslaught by Russia on its eastern flank.
Addressing Americans from the White House's Roosevelt Room, Biden pledged to send heavy artillery, dozens of howitzers, and 144,000 rounds of ammunition, as well as tactical drones, as he called on Congress for supplemental funding to provide additional aid for Kyiv.
Biden also announced $500 million in direct economic assistance to the Ukrainian government as it battles to save the lives of people under siege by Russian forces.
"We’re in a critical window now of time where they’re going to set the stage for the next phase of this war,” Biden said. The United States and allies are “moving as fast as possible” to provide Ukraine with the equipment and weapons it needs.
Biden said the new assistance will expend most of the remaining funds available for this purpose and that he will make a supplemental funding request to Congress next week. He said the amount is being discussed.
"That’s being decided now. I’m asking the Defense Department to put together a proposal," he said.
Biden spoke after face-to-face talks with Ukrainian Prime Minister Denys Shmyhal, who is in Washington for a variety of meetings.
The president announced plans to ban Russian-affiliated ships from docking at U.S. ports, as previously reported by Reuters, further ratcheting up pressure on Moscow.
The new arms package is the same size as an $800 million one announced last week
Biden said the new weapons are needed as Ukraine battles a major offensive from Russia in the east, where the flatter terrain requires a different set of weaponry.
On Wednesday, he convened U.S. military leaders in an annual White House gathering that took on special significance as the war enters a risky new phase.
Russia has said it has entered a new stage of its operation and is methodically seeking to "liberate" the Donbas region of eastern Ukraine. Western allies anticipate Russia's campaign could last many months, grind to a stalemate and test the battlefield capabilities of Ukrainian fighters.
Biden disputed Russian claims of control of the embattled city of Mariupol, saying that "there's no evidence that Mariupol has completely fallen." He added that Russia "should allow humanitarian corridors to let people at that steel mill and other places (that) are buried under rubble to get out."
Russia says it launched what it calls a "special military operation" on Feb. 24 to demilitarize and "denazify" Ukraine. Kyiv and its Western allies reject that as a false pretext.
U.S. forces are not fighting in Ukraine but are indirectly engaged, arming, training and financing its forces.
The U.S. aid announced last week included artillery systems, artillery rounds, armored personnel carriers and unmanned coastal defense boats, broadening the scope of materiel sent to Kyiv to include new types of heavy equipment.
Adding this week's package brings total U.S. military aid to Ukraine since Russia invaded to well over $3 billion.
