Protests have taken place for a third consecutive night in Lebanon’s capital, Beirut, amid mounting anger over the devastating explosion a week ago that reportedly killed more than 200 people.
Clashes broke out near the parliament building, with demonstrators throwing fireworks and police firing tear gas.
Hours earlier, the Lebanese cabinet submitted its resignation.
Prime Minister Hassan Diab blamed the blast on years of endemic corruption but avoided taking responsibility.
A fire is believed to have caused the detonation of 2,750 tonnes of ammonium nitrate that had been stored for six years without safety measures at Beirut’s port.
The blast wave flattened nearby buildings and caused extensive damage over much of the rest of the city, leaving hundreds of thousands of people homeless.
Lebanon was already struggling with an unprecedented economic crisis before the disaster, with families pushed into poverty and hunger.
Since October, protesters have been demanding the complete overhaul of the political system, which they blame for government corruption and mismanagement.
