Rescue workers in Lebanon are searching for more than 100 people who are missing one day after a huge explosion devastated the port area of the capital, Beirut.
The blast, which shook the whole city, killed at least 100 people and injured more than 4,000 others.
President Michel Aoun said the blast was caused by 2,750 tonnes of ammonium nitrate stored unsafely in a warehouse.
All port officials have been put under house arrest pending an investigation.
Customs chief Badri Daher told local media that his agency had repeatedly called for the ammonium nitrate to be removed, but “this did not happen, and we leave it to the experts to determine the reasons”.
Ammonium nitrate is used as a fertiliser in agriculture and as an explosive.
President Aoun has declared three days of mourning. Opening an emergency cabinet meeting, he said: “No words can describe the horror that has hit Beirut last night, turning it into a disaster-stricken city”.
The explosion occurred just after 18:00 (15:00 GMT) after a fire at the port, and it was felt 240km (150 miles) away on the island of Cyprus, in the eastern Mediterranean.
