Dozens were injured Wednesday when Lebanese police clashed with protesters demanding accountability for last year's Beirut port explosion, a short distance from the main event marking the tragedy's first anniversary.
Scuffles in central Beirut broke out between riot police and stone-lobbing protesters, who lit a fire and tried to storm the parliament's headquarters, whose members have been accused of stalling a probe into the disaster.
Riot police responded by firing tear gas, rubber bullets and water canons, and urging "peaceful protesters" to leave.
"In light of repeated attacks on members of the Internal Security Forces, we will resort to legitimate and proportionate means ... against non-peaceful demonstrators," police said in a statement.
Shortly afterwards, Lebanese television appeared to show a tank moving in to the area.
The Red Cross, which dispatched 21 ambulances and 100 paramedics, said it transported eight people to hospital, and had treated dozens more on-site.
Nearby, a few hundred of metres (yards) away at the port, thousands gathered to mark the first anniversary of the explosion which killed at least 214 people.
Survivors and relatives of blast victims carried flags and portraits of the dead, as prayers and mournful tunes rang out amid a mix of grief and anger.
There were no reports of violence there.
Shortly after 6:00 pm on August 4, 2020, a stock of ammonium nitrate fertiliser haphazardly stored at the city's port exploded and left swathes of the Lebanese capital looking like a war zone.
One year on, no senior official has been held to account. A local investigation has yet to yield major arrests or even identify a culprit, with political leaders widely accused of obstructing justice.
