The Lebanese army said on Sunday that 25 soldiers were injured while trying to maintain order in a protest in Beirut a day earlier, the National News Agency (NNA) reported.
The soldiers were also trying to open the roads that were cut off by protesters and prevent destruction of public and private properties in the Lebanese capital, the army added.
Hundreds of protesters demonstrated on Saturday in downtown Beirut, calling for the overhaul of the Lebanese political system.
They threw stones at security forces and smashed the windows of the shops near the parliament.
Meanwhile, riot police fired tear gas at demonstrators to disperse them.
The Lebanese have been suffering from dire economic circumstances in the past few months after policies by previous governments failed and have led to an accumulated public debt of more than $89 billion.
