A main terrorist suspect was killed during a raid in Lebanon's northern port city of Tripoli on Sunday, a security source told Xinhua.
The source said the Information Branch of the Internal Security Forces raided a residential complex in Tripoli where Monzer Al Hassan stayed.
The source said Hassan, who held a Swedish citizenship, was suspected of providing explosives to two suicide bombers who blew themselves up when police raided their Beirut hotel on June 25.
