A roadside bomb exploded Tuesday near a United Nations patrol south of Beirut, lightly wounding two peacekeepers, UN and Lebanese officials said. The explosion rocked the town of Rmeileh, near the southern coastal city of Sidon. Smoke was seen billowing from the scene, witnesses said. Milos Strugar, adviser to the force commander of the UN Interim Force in Lebanon, said one UNIFIL vehicle was damaged in the explosion and two peacekeepers in the vehicle were "lightly wounded" and taken to a hospital. Strugar would not confirm the nationalities of those hurt, but he said they were not members of the Spanish contingent, as earlier reported by Lebanese officials. Two Lebanese security officials also described the attack, both on condition of anonymity in line with Lebanese military regulations.
