Poland says the missile strike on its land appears to be an accident by Ukraine

Poland's president said Wednesday that it appears a missile that landed just inside the country's border was from Ukraine in what he called an "unfortunate accident."

"We have no evidence at the moment that it was a rocket launched by Russian forces," President Andrzej Duda said.

"However, there are many indications that it was a missile that was used by Ukraine's anti-missile defense."

Two Polish citizens were killed Tuesday when the missile came crashing down in a rural village in eastern Poland, 

just a few miles from the western border of Ukraine.

This happened amid a Russian barrage of missiles fired at cities across Ukraine, with Ukraine responding with its air defense systems.

NATO members discussed the issue in Brussels, and the secretary general of alliance, Jens Stoltenberg, said a preliminary analysis pointed to a Ukrainian air defense missile that had been fired at an incoming Russian missile.
