Col. Diego Fulco, a spokesman for the force known as UNIFIL, says the troops were driving in the area of Rashaya al-Fukhar Saturday when their vehicle went off the road.

Three other peacekeepers were injured. He says no other vehicles were involved but gave no other details.

Fulco did not reveal the nationalities of the victims.

Lebanon's state-run news agency, however, said they were French. The circumstances of the accident were being investigated.

The peacekeeping mission has about 12,100 military personnel from 30 countries.
