A Polish military transport plane has crashed in northwestern Poland, killing at least seven of the 18 people on board.
A military spokesman says the plane was carrying 14 passengers and four crew members.
Emergency services officials say the Spanish-made CASA aircraft crashed in a wooded area as it approached a military base at Miroslawiec late Wednesday.
The passengers were officers who were returning from an air safety conference in Warsaw.
