Twenty people from the Polish Air Force returning from a flight-safety conference had been killed when a transport plane crashed.

Authorities had first said that the crash on Wednesday evening killed seven people.

A general was among the 16 passengers and 4 crew members who were killed.

It was the first accident in Poland involving that type of plane, which is generally considered an extremely reliable aircraft.
"Soldiers, husbands and fathers have died, and that is the most tragic result of this catastrophe," said Prime Minister Donald Tusk
