Seven people have died in a mid-air collision in Slovakia between two planes carrying parachutists .
The four pilots and three parachutists who were killed were taking part in rehearsals for an air show.
"Soon after takeoff, after the first manoeuvre, the two planes collided due to causes that are not yet known," said Interior Minister Robert Kalinak.
Thirty-one parachutists managed to jump 1,500m (4,921ft) to safety, with five suffering minor injuries.
Wreckage was discovered in a forested area near
the western town of Cerveny Kamen.
All of those on board were training for an air show this weekend in Slavnica.
Mr Gyenes told the TA3 news channel that the accident may have been the result of overloading, which made one of the planes suddenly lose altitude.
The air show has now been cancelled, local media say.(bbceurope)
