A Spanish soldier serving with the United Nations Interim Force in Lebanon was killed on Sunday in a road accident in the south of the country and two fellow soldiers were injured, Lebanese and UNIFIL officials said.

The officials said the vehicle in which the three soldiers were riding in the village of Blat overturned killing one soldier. No other vehicles were involved in the accident, they said.

A UNIFIL military spokesman told AFP that two other soldiers were slightly injured. He would not specify the nationality of the soldiers but a Lebanese security official said they were serving with the Spanish UNIFIL contingent.

UNIFIL, which was set up in 1978 to monitor the border between Israel and southern Lebanon, was considerably beefed up in the wake of the 2006 war between Israeli forces and Hizbullah fighters.(AFP)
