The leader of Hezbollah has implied that Israel was behind the killing of Rafik al-Hariri, the former Lebanese prime minister who was murdered in 2005.

Sayyed Hassan Nasrallah was speaking for the first time since the indictment on Thursday by the UN Special Tribunal for Lebanon of four members of the Lebanese movement over the murder of Hariri.
