Allies Deliver Fighter Jets to Bolster Ukraine's Defenses amid Russian Advances

Slovakia transferred all 13 promised MiG-29 fighter jets to Ukraine by land.
Germany approved Poland's request to send five additional MiG-29s from old East German stocks to Ukraine.
The new fighter jets will strengthen Ukraine's air force, but the country urgently needs more air-defense ammunition to counter Russia.
US officials worry Ukraine could run out of air-defense weapons and ammunition by late spring or early summer without further aid.
Western countries are focusing security assistance on providing Ukraine air-defense ammunition.
