A EU peacekeeping helicopter belonging to the Spanish military crashed Thursday in Bosnia with four crew members on board, officials said.

The helicopter went down around midday north of the town of Travnik, said Lt. Cmdr. Kerry Corkett, a spokesman for the peacekeeping force, which is also known as EUFOR. The status of the crew was not immediately clear.

Spain's Defense Ministry said the helicopter belonged to its military and that it was carrying two Spaniards and two German officers as passengers. The ministry said the helicopter went down near the north-central city of Banja Luka.

The discrepancy in the location of the crash could not immediately be explained.

Corkett said a second helicopter on the same route had confirmed the crash. A rescue operation was under way. No further details were immediately available.
