KYIV, Ukraine (AP) — Russia launched its third massive missile attack on Ukraine in the past four days, and the second to target the capital of Kyiv, with Poland's military saying that one of the missiles launched at western Ukraine briefly entered its airspace Sunday.

The head of Kyiv's military administration, Serhiy Popko, said Russia used cruise missiles launched from Tu-95MS strategic bombers. An air alert in the capital lasted for more than two hours as rockets entered Kyiv in groups from the north.

He said the attacks were launched from the Engels district in the Saratov region of Russia.

According to preliminary data, there were no casualties or damage in the capital, he said.

The operation command of Poland, a member of NATO, said in a statement that there was a violation of Polish airspace at 4:23 a.m. (0323GMT) by one of the cruise missiles launched by Russia against towns in western Ukraine.

The object entered near the Polish town of Oserdów and stayed there for 39 seconds, the statement said. It added that military radar systems observed the missile the entire time and all necessary procedures were launched to ensure the safety of Polish airspace.
