A school outing ended in catastrophe in eastern Uganda on Thursday evening, when a bus full of children lost control on a notoriously dangerous hill and crashed, killing at least 20 pupils.

What happened

The pupils, from King David Junior School in Ndejje, were returning from a study tour when their bus reached Chekwatit Hill, in Kowo Sub-county of Kapchorwa District, in the country's mountainous east. According to officials, the bus developed a mechanical fault and the driver lost control before it crashed at about 8 p.m. Uganda's minister of local government, who went to the scene, said at least 20 pupils and an adult, described as the school's founder, were killed, and more than 60 people were hurt. The most seriously injured were taken to a regional hospital, where several children were reported in critical condition.

A deadly stretch of road

The site of the crash is grimly familiar to Ugandans. Chekwatit Hill is widely known as an accident black spot, a steep, winding stretch that has claimed lives before. Its gradient and poor conditions leave little margin for error when a vehicle fails, and on Thursday, with a bus full of children aboard, that margin ran out.

A wider crisis

The disaster is part of a broader and persistent problem. Road crashes are among the leading causes of death in Uganda, the toll driven by aging and poorly maintained vehicles, difficult roads, and uneven enforcement of safety rules. Buses used to ferry schoolchildren have figured in a series of deadly accidents, raising repeated questions about inspections, maintenance and driver oversight that have not translated into lasting change.

For the community around King David Junior School, those systemic failures are, on Thursday night, a specific and unbearable grief: a bus that set out full of children on an ordinary school trip, and did not bring them all home. Ugandan authorities said they had opened an investigation into the crash and would examine the bus's condition and the circumstances that led it to leave the road.
