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.
