Seventeen members of the Colombian security forces have died in a helicopter crash north-west of Bogota, the army has said.

The wreckage of the army helicopter was found on Monday in Pensilvania in the central province of Caldas, a day after the aircraft had gone missing.

The army said it suspected bad weather may have been to blame for the crash.

Accidents are not uncommon in this area as mountain ranges and unpredictable weather make flying difficult.
