Ukraine insists on the complete closure of the sky over its territory, Deputy Minister of Infrastructure Mustafa-Masi Nayyem has said.

"Given the inadequate actions of the aggressor country, the constant disregard for all international rules and norms, Ukraine insists on the complete closure of the sky over Ukraine. So far, this concerns the protection not only of our country, but also of the citizens of NATO countries," Nayyem wrote in his Telegram on Thursday.

He, in particular, spoke about the negotiations with US Secretary of Transportation Pete Buttigieg regarding systemic measures to support Ukraine in the fight against the aggressor.

"In the conversation, Buttigieg confirmed that the United States is ready to help as much as possible in the process of restoring Ukrainian infrastructure after the war and the de-occupation of Ukrainian territories," Nayyem said.

According to Nayyem, the United States is also tightening sanctions against Russia. They have closed their own skies for Russian aircraft.

Nayyem said that, in the opinion of the Ukrainian side, the next logical sanctions measure should be blocking, following the UK and Canada, servicing ships of Russian or related companies in ports, as well as assisting in the exclusion of Russia and its organizations from key international associations.

"The focus is on the supply of lethal weapons, medical supplies and humanitarian aid to Ukraine. It will increase, and for this, new supply routes are being developed from the United States through European countries to Ukraine," the Deputy Minister said.
