The bodyguard of a senior Lebanese intelligence officer has been killed near the southern city of Sidon. The officer – Colonel Samir Shehadeh – was seriously injured along with four others when a bomb exploded as two cars carrying him and his companions passed through the coastal village of Rmeileh. Shehadeh was in the second. Sergeant Wissam Harb, who was sitting in the front seat of the first, took the full force of the blast. No one has claimed responsibility for the attack but Shehadeh, who works for the Interior Ministry, played a leading role in Lebanon’s inquiry into last year’s assassination of former Prime Minister Rafik al-Hariri. Over the next few weeks Beirut plans to authorise an international tribunal to try the suspects. An initial UN report said Syrian security officials and their allies in Lebanon were involved in Hariri’s death.
