Russia launched what the head of Ukraine's armed forces called "massive" missile strikes Thursday, as Moscow hurled 55 air and sea-based missiles at targets including the capital Kyiv.
Ukraine President Volodymyr Zelenskyy said his country had "defeated" Russia's attempt to intimidate it through the attacks.
The attacks come after the U.S. and Germany's momentous decision Wednesday to send battle tanks to Ukraine. Now, talk has turned to the possible supply of other firepower, namely fighter jets.
Zelenskyy thanked Kyiv's allies for supplying tanks, but said he had asked NATO Secretary General Jens Stoltenberg for more assistance.
"We have to unlock the supply of long-range missiles to Ukraine, it is important for us to expand our cooperation in artillery, we have to achieve the supply of aircraft to Ukraine. And this is a dream. And this is a task," he said in his nightly address.
Ukraine has made no secret that it would like to receive fighter jets, such as the U.S. F-16s, from its allies to help it fight Russia. An advisor to Ukraine's defense ministry told CNBC on Thursday that Ukraine is determined to get fighter jets from its allies.
Meanwhile, the Biden administration announced fresh sanctions targeting groups that support the Russian war effort, including paramilitary firm Wagner Group.
