The Lebanese army says troops have confiscated a drone in the eastern Bekaa Valley as it was being taken to insurgents on the Syrian side of the border.

The army said Wednesday the Flying Cam drone was to be used for spying on Lebanese army positions. It added that an investigation has begun to know where the drone came from.

In August, Islamic militants crossed from Syria into the Lebanese border town of Arsal, capturing more than 20 Lebanese soldiers and police officers. The militants have killed four of them.

Since then, it has been common for the Lebanese army to shell militant positions on the Lebanon-Syria border.

The army said companies that sell such drones should know the identity of the buyers and what will they use it for.
