Lebanese Prime Minister Saad Hariri announced his resignation after 13 days of protests over political corruption and economic turmoil.
His television address came shortly after the violence erupted in the street when supporters of two Shiite groups attacked a protest camp and obstacle in Beirut.
Tents are lit and anti-government protesters beat. Some chanted in support of Hezbollah – a powerful force in the coalition government – and the Shi'ite political party Amal.
Police and riot troops responded with tear gas and by the end of the day, anti-government protesters were back on the streets celebrating Mr Hariri's message.
