Tear gas was deployed against protesters to stop them from advancing on Nejmeh Square and parliament, in Beirut, on Monday.
Hundreds of protesters marched in Beirut demanding the resignation of the government and Lebanese President Michel Aoun in the aftermath of the deadly explosions which rocked the city's port last week.
Lebanon's Prime Minister Hassan Diab, Justice Minister Marie Claude Najm, Information Minister Manal Abdel Samad, and Environment Minister Damianos Kattar have all announced their resignation following protests over the weekend. If a total of seven ministers resign, the cabinet would become a caretaker government, until a new government is formed.
The blasts, which took the lives of at least 200 people and injured more than 5,000, according to officials, are thought to have been caused by the still unexplained ignition of 2,750 tonnes of ammonium nitrate, a highly explosive chemical material which was reportedly stored without precautionary measures at the port, according to Diab.
