A small explosion killed one and wounded another in the Kuwaiti information office in Beirut on Monday, a security source said.
The explosion appeared to be caused by a booby-trapped package delivered to the office, the source said. The wounded were two Lebanese men working at the office, he added.
Security forces cordoned-off the area leading to the scene.
A series of explosions have rocked Lebanon since the February assassination of former Prime Minister Rafik al-Hariri, which many Lebanese blame on Syria. Damascus has repeatedly denied any role.
