"The army command... calls on citizens to be wary of plots aimed at taking Lebanon backwards and dragging it into an absurd war," a statement said, adding that it would give an "armed response to any armed action".
One person was killed and seven wounded in a clash in the heart of Lebanon's second-largest city Tripoli on Thursday in the latest in a spate of deadly violence between Lebanese supporters and opponents of the Damascus regime.
Sniper activity renewed on Thursday in the northern city of Tripoli as the army began a series of raids to detain offenders and seized weapons from a depot in the wheat market.
According to a communique issued by the army the arms depot included a quantity of explosives, local-made mortars, rifles and ammunition and other military equipment.
The army vowed to continue pursuing gunmen, warning that it will not hesitate in responding to those who are violating security.
The state-run National News Agency earlier reported that the army patrolled the streets separating the rival neighborhoods of Alawite Jabal Mohsen and Sunni Bab al-Tabbaneh.
Media reports said that an officer and several soldiers were injured in the wheat market and in Bohsas after unknown assailants opened fire at their patrol.
On Wednesday the Army Command vowed in a statement that it will take decisive measures to address the thorny situation in Tripoli away from any political interference.
