The clashes broke out shortly before sunset Sunday when angry protesters tried to break through barbed wire leading to the government's headquarters.
Police also beat back protesters with clubs. The protesters hurled stones and water bottles at the force, injuring at least two who were seen whisked away by their comrades.
The violence comes hours after Prime Minister Tammam Salam hinted he might step down following Saturday's violent protests triggered by a monthlong trash crisis. Clashes that day injured more than 100 people.
