Lebanese called for protests outside Baabda palace on Monday to demand President Michel Aoun step down after a massive explosion that has ignited anti-government protests and resignations by several ministers, with the justice minister the latest to go.

Last week’s port warehouse detonation of more than 2,000 tonnes of ammonium nitrate killed 158 people, injured more than 6,000 and destroyed a swathe of the Mediterrnean city, compounding months of political and economic meltdown and prompting furious calls for the entire government to step down.

The cabinet, formed in January with the backing of the powerful Iran-backed Hezbollah group and its allies, was due to meet on Monday under pressure with many ministers wanting to resign, ministerial and political sources said.

The information and environment ministers quit on Sunday as well as several lawmakers. The justice minister resigned on Monday, citing the catastrophic explosion.
