International leaders will hold talks on Sunday to raise aid for Beirut, five days after teh massive explosion which devastated the Lebanese capital.
The virtual conference – set up by France and the United Nations – starts at 14:00 Lebanon time (11:00 GMT).
US President Donald Trump has said he plans to join the call.
Officials estimate the blast at the warehouse, which stored 2,000 tonnes of ammonium nitrate, caused up to $15 billion (£11.5bn) in damage.
The explosion left at least 158 people dead, 5,000 injured and 300,000 homeless.
On Saturday several thousand people took to the streets, with police firing tear gas at stone-throwing protesters and some demonstrators storming government ministries.
In a televised address, Lebanese PM Hassan Diab said he would ask for early elections as a way out of the crisis. The issue will be discussed in the cabinet on Monday.
Lebanon was already mired in a deep economic crisis and struggling to tackle the coronavirus pandemic before the explosion tore through Beirut.
An anti-government protest movement erupted last October, fuelled by the financial situation and a collapsing currency.
