At least 20 people have been killed when a military ammunition depot in Tanzania's largest city blew up in a series of explosions.
The blasts flattened homes and left more than 140 people injured.
Thousands ran for their lives from blasts that were felt 12 miles away.
Prime minister Mizengo Pinda said several houses and a school were destroyed in the explosions, which sent huge orange bursts into the sky over Dar es Salaam.
Debris showered parts of the city 10 miles from the Gongola Mboto military base where the depot is located.
It was at least the second such ammunition depot explosion at a military base in Dar es Salaam since 2009.
Military spokesman Lt Col Kapambala Mgawe said the explosions were accidental, but gave no further details.
The blasts closed the city's international airport, which is near the Gongola Mboto military base.
Some 4,000 residents were evacuated to the national stadium in Dar es Salaam, which lies along the Indian Ocean in East Africa.
