Armed Hezbollah militants warded off members of the United Nations Interim Force in Lebanon (UNIFIL) last month when the peacekeepers discovered a truck carrying weapons and ammunition belonging to the Lebanon-based guerilla group.

The incident was referred to briefly in a semi-yearly report submitted to the UN Security Council by UN Secretary General Ban Ki-Moon. The incident was the first time that UNIFIL forces were confronted by armed Hezbollah men south of Lebanon's Litani River, an area which Security Council resolution 1701 prohibits Hezbollah from entering.

According to a government source in Jerusalem, the incident caused great embarrassment for UNIFIL. The source described the incident, explaining that UNIFIL troops on patrol discovered the truck and chased it down and pulled it over. When the UNIFIL troops approached the vehicle, the source said, armed Hezbollah men exited the truck and threatened the troops at gunpoint. The UNIFIL patrol then went back into their cars, according to the source, and returned to their base.

The report submitted to the Security Council said the incident occurred on the night between the 30 and 31 of March. "This serious violation of the UN resolution raises concerns," the report said.

The incident was not reported in the media at the time of its occurrence...
