Russia-Ukraine updates: US to ban Russian carriers from its airspace

Ukrainian President Volodymyr Zelenskyy provided a televised update on the Russian invasion and said his family is in hiding due to threats on their lives.

"The enemy has identified me as target No. 1 and my family as target No. 2. They want to destroy Ukraine politically by destroying the head of state," the president said.

Zelenskyy said he is staying in the government quarter "with everyone who is needed for the work of the central government." He reiterated that he and his family are not "traitors."

The president warned residents that "enemy sabotage groups have entered Kyiv."

"I am asking the residents very much: be careful, [and] follow the rules of the curfew," he said.

Zelenskyy said as of Thursday evening at least 137 people had been killed during the invasion, including 10 officers and 13 border guards.

Additionally, the president said at least 316 people have been wounded so far during the attacks.

Ukrainian Defense Minister Oleksiy Resnikov put out a statement Thursday evening, saying the country is repelling the Russian invasion but warning of new attacks to come.

"The Kremlin is planning a new wave of attacks, including using paratroopers, but our army is ready to meet them," he said.

Resnikov said that the situation remains "difficult" in the south and that heavy fighting is continuing in the Sumsky region to the north of Kyiv.

He hailed the international sanctions issued against Russia as well as the rallies in several Russian cities protesting Putin's invasion.

"Tomorrow, Russia will learn the price of the Putinist insanity. We are on our soil and we will resist. And we will definitely win," Resnikov said.

"Our whole people is gradually joining the resistance," he said. "The enemy did not expect such resistance."

Ukrainian officials said they have reclaimed a key military airport on the edge of Kyiv that had been seized by Russian special forces.

The Ukrainian Parliament’s official Telegram account said the Antonov Airport in Hostomel was now "fully under the control" of Ukrainian troops.

Deputy Interior Minister Anton Gerashchenko also said Ukrainian troops had managed to retake the airport, calling it “the first big victory!”

The move comes as the county prepares to bolster its forces.

President Volodymyr Zelenskyy ordered a general mobilization that calls up men of fighting age and reservists.

The order also allows the government to commandeer transport.
