At least five people were killed after a shooting broke out in Beirut during a protest by the chief judge in the investigation into last year’s port explosion that killed more than 200 people.
Hezbollah and its allies had called for protests against the investigation, saying they want Judge Tarek Bitar to be removed from office.
There was a large military presence in the streets of the Lebanese capital, with snipers, pistols, rifles and rocket-propelled grenades being fired upon.
At least five people were killed in the clashes, according to the interior minister.
Mr. Bitar is the second judge to lead the investigation. Hezbollah has accused him of singling out politicians for questioning, most of them allies of the group.
The Lebanese government is only a few months old and is already dealing with a series of crises in the country.
The initial cause of the shooting is unclear.
