Lebanon army deployed in streets to ease tension
The army has been deployed on the streets of Lebanon's two biggest cities, Beirut and Tripoli, in efforts to bring calm after the death of a senior security official last week.
The army is a widely respected institution in the country, and it has often been required to soothe tensions between the country's diverse political and religious factions.
