A Lebanese police officer was wounded Tuesday in southern Lebanon in an explosion that was an apparent assassination attempt, security officials said. Lt. Col. Samir Shehade was critically injured in the explosion, which went off near his car in the village of Rmaile near the southern port city of Sidon. It was not clear whether the bomb was placed under or near his car, said the officials. Al-Arabiya TV station said Shehade had been involved in the arrest in August last year of four pro-Syrian Lebanese generals in Lebanon. The four were arrested on suspicion of involvement in the February 2005 assassination of former Lebanese prime minister Rafik Hariri.
