The White House announced a new USD 400 million military aid package for Ukraine on Thursday that will include air defense systems, writes DW.

Jake Sullivan, the White House national security adviser, said the package includes “important air defense contributions” such as missiles for Hawk air defense systems as well as US Avenger air defense systems that come equipped with Stinger missiles.

According to the Pentagon statement, the package will also include additional ammunition for High Mobility Artillery Rocket Systems (HIMARS) and other weapon systems, 100 High Mobility Multipurpose Wheeled Vehicles (HMMWVs), 400 grenade launchers, demolition equipment for obstacle clearing, and cold weather protective gear.

Sullivan also said the United States has detected some signs that Russian forces may be planning to withdraw from the Ukraine city of Kherson.

He said that the Russian withdrawal from some areas in Ukraine does not mean the Ukraine war is concluding. Sullivan added that Washington was not pressuring Ukraine to engage in diplomacy with Russia over the war.
