 A magnitude 5.7 earthquake has killed at least 13 people and injured 203 in northern Tanzania, the authorities say. The quake struck near the western shore of Lake Victoria outside in the city of Bukoba, population 70,000, where a majority of the casualties were reported. 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. The U.S. Geological Survey said the quake could be felt as far away as western Kenya and was unusually strong for the region. "This incident has caused a lot of damage," Deodatus Kinawila, the district commissioner of Bukoba, told the BBC. Even the number of injuries is likely to go up." 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).
– Eleven people have been confirmed killed in a 5.7-magnitude earthquake that struck Tanzania Saturday afternoon, but the actual death toll is feared to be much higher, the BBC reports. According to UPI, the earthquake—which the US Geological Survey says was "unusually strong" for the area—struck shortly before 3:30pm local time near Lake Victoria on the border with Rwanda and Uganda. The shallow quake originated only 6 miles below the surface, the AP reports. Shallow quakes typically cause more damage. The city of Bukoba, with a population of 70,000, appears to have been the hardest hit. Photos of collapsed buildings in the city were posted to social media, and the quake's 11 confirmed casualties were people in brick structures in Bukoba when the quake struck. Authorities say 192 people have been confirmed injured in addition to the deaths, but one one authority tells the BBC both numbers are "likely to go up." Local hospitals are already full and having difficulty dealing with the waves of injured.
