The Biden administration will send Ukraine a new $725 million package of weapons and other military assistance, the White House said Friday, as the U.S. added to a flurry of aid announcements from European allies this week.

The announcement comes on the heels of meetings at NATO, where defense leaders from Europe and around the world pledged weapons and air defense systems to Ukraine as Russia heightened its bombardment of Kyiv and other regions.

Officials said there are no major new weapons in the U.S. package. Instead, the U.S. aid is largely aimed at restocking thousands of rounds of ammunition for the weapons systems Ukraine has been successfully using in its counteroffensive against Russia, as the war stretches into its eighth month.
