A magnitude 5.7 earthquake has killed at least 13 people and injured 203 in northern Tanzania, the authorities say.
The quake struck close to the border with Uganda and Rwanda near Lake Victoria.
Images posted on social media showed significant damage to buildings in Bukoba, a city of more than 70,000 people where most casualties were reported.
Tremors were felt as far away as western Kenya.
"This incident has caused a lot of damage," Deodatus Kinawila, the district commissioner of Bukoba, told the BBC.
"For now, the situation is calm and under control," he said later.

"Some people have been discharged from hospital," he added. "We don't expect many more injuries."
The US Geological Survey says the quake struck at a depth of 10km (six miles) at 15:27 local time on Saturday (12:27 GMT).

I felt it strong yesterday. So the whole Rift valley shook?

Are we safe on the rift? It like living on an active volcano
