Beirut bombing kills 4, including Lebanese intelligence officer

BEIRUT (CNN) - An explosion in a Beirut suburb killed four people, including Lebanon's top anti-terror investigating officer and his driver Friday, sources with the Lebanese Internal Security Forces and a government minister told CNN. The attack also wounded 38 people, security sources said.

"It was a powerful blast," CNN's Anthony Mills said. "I was less than half a mile away when it occurred and I felt the shock waves in the car I was traveling in. I arrived on the scene several minutes later and there was widespread damage - several vehicles that had been reduced to hulks of burning, twisted metal ... debris scattered over a wide area."

The explosion killed Capt. Wissam Eid, the sources said, who was also the target of a hand grenade attack at his home in February 2006.
