Ukraine received a Stinger anti-aircraft missile system and ammunition by plane from Lithuania on Sunday, the Defense Ministry in Kiev said.
Earlier on Sunday, two other planes had delivered about 180 tonnes of ammunition from the United States, Defense Minister Oleksii Reznikov said. Ukraine has so far received nearly 1,500 tonnes of ammunition delivered on 17 flights, he said via Twitter.
Military officials say Ukraine has significantly bolstered its military with the help of allies, equipping the army especially with US and British anti-tank systems and Turkish drones.
The United States and allies say Russia could invade Ukraine at any time. Russia, which has troops close to Ukraine, denies having such a plan.
