Lebanon's prime minister announced his government's resignation on Monday, saying a huge explosion that devastated the capital and stirred public outrage was the result of endemic corruption.
The Augst 4 detonation at a port warehouse of more than 2,000 tonnes of ammonium nitrate killed at least 163 people, injured more than 6,000 and destroyed swathes of the Mediterranean capital, compounding months of political and economic meltdown.
In a televised address, Prime Minister Hassan Diab said he backed calls by ordinary Lebanese for those responsible for quote "this crime" to be put on trial.
Diab made the announcement after the cabinet, formed in January with the backing of the powerful Iranian-backed Hezbollah group and its allies, met on Monday.
Many ministers wanted to resign, according to ministerial and political sources.
Diab said on Saturday he would request early parliamentary elections.
Demonstrations broke out again in central Beirut, with some protesters hurling rocks at security forces guarding an entrance leading to the parliament building, who responded with tear gas.
For many ordinary Lebanese, the explosion was the last straw in a protracted crisis over the collapse of the economy, corruption, waste and dysfunctional governance, and they have taken to the streets demanding root-and-branch change.
