At least 78 people died with more than 4,000 left injured in a huge explosion in Lebanon’s capital Beirut. The blast began with a fire at the port that exploded into a mushroom cloud, shaking the whole city on Tuesday.

Prime Minister Hassan Diab said at a defence council meeting that about 2,750 tonnes of ammonium nitrate was stored in the Beirut port warehouse, unsafely for past six years.

“It is unacceptable that a shipment of 2,750 tonnes of ammonium nitrate has been present for six years in a warehouse, without taking preventive measures,” a spokesman said at a press conference as per AFP.

“It is unacceptable and we cannot remain silent on this issue,” the spokesperson added.

According to a report published in BBC, President Michel Aoun has scheduled an urgent cabinet meeting for Wednesday, announcing the emergency funds of 100 billion lira (£50.5m; $66m). He is also planning to declare a two-week state of emergency.

An official period of mourning will be observed in Lebanon for three days from Wednesday.
