Security forces fired rubber bullets and tear gas as violence between police and anti-government protesters in Lebanon flared up.
The violence was some of the worst in the capital Beirut since demonstrations began two months ago.
For first time in Beirut, anti-riot police fired rubber bullets at protesters, whom they chased away from the city centre.
It was not clear what caused the harsh crackdown meted out against the anti-government protesters following earlier clashes with those who attacked the protest camp.
The tension comes only two days before the president meets with parliamentary blocs to name a prime minister.
Earlier consultations were postponed amid the failure of rival political groups to agree on a new head of government.
Protesters have been calling for a new government unaffiliated with establishment political parties after the government headed by former Prime Minister Saad Hariri resigned in October.
We know everyone is suffering under the Tories - but the Canary is a vital weapon in our fight back, and we need your support
The Canary Workers’ Co-op knows life is hard. The Tories are waging a class war against us we’re all having to fight. But like trade unions and community organising, truly independent working-class media is a vital weapon in our armoury.
The Canary doesn’t have the budget of the corporate media. In fact, our income is over 1,000 times less than the Guardian’s. What we do have is a radical agenda that disrupts power and amplifies marginalised communities. But we can only do this with our readers’ support.
So please, help us continue to spread messages of resistance and hope. Even the smallest donation would mean the world to us.
