A Hezbollah fighter shot down a Lebanese army helicopter last week, said the movement leader, Hassan Nasrallah, adding that the shooting was a mistake. The Hezbollah fighter opened fire after being taken by surprise, when the aircraft landed nearby.
One of the pilots was killed and the helicopter was forced to crash-land.
Widespread criticism has been faced by the militant and political movement over the shooting.
The man who shot at the helicopter was described by Mr Nasrallah as an “honorable resistor” who had asked to be handed over to the Lebanese judicial authorities.
Hezbollah says it is co-operating fully with the investigation into the incident.
The group is militarily far stronger than the Lebanese national army.
And although the movement’s continued deployment in southern Lebanon and its holding on to its weapons are highly controversial issues, a policy statement issued by Lebanon’s national unity government recognises Hezbollah’s right to use all means possible to “liberate” Lebanese land, which the country says is occupied by Israel.
