Beirut has received a stream of international assistance since the blast, and on Thursday hosted French President Emmanuel Macron, who pressed Lebanese leaders for deep reform ahead of an aid conference planned in the coming days.
Shock has turned to anger in Lebanon since Tuesday's colossal explosion devastated swathes of the capital, with security forces firing tear gas at demonstrators who gathered near parliament late Thursday.
The revelation that a huge shipment of hazardous ammonium nitrate fertiliser had languished for years in a warehouse in the heart of the capital served as shocking proof to many Lebanese of the rot at the core of their political system.
People are enraged over what they deem gross negligence, and recklessness on behalf of the authorities, who did not take action to safeguard the lives of the Lebanese, despite having knowledge of the existence of the extremely dangerous material at the Beirut Port.
