Poland has scrambled two F-16 fighter jets to intercept a Russian Il-20 reconnaissance aircraft flying around 40km north of Kolobrzeg over the Baltic Sea, the country's defence minister has said.

Poland scrambled fighter jets to secure its airspace after Russian air strikes killed at least 13 in neighbouring Ukraine, including one in Kyiv.

The missile flew for roughly six minutes in Polish airspace before crashing 60 miles deep into the country, the military said.
