Twenty schoolchildren have died after the bus carrying them crashed on the way back from an educational excursion in eastern Uganda, authorities said.
Uganda suspended school closures on Friday after the accident, which also killed an adult on Thursday evening.
Three other adults and more than a dozen children were also injured, officials said.
The bus belonging to King David Junior School was returning to the capital, Kampala, after a trip to Sipi Falls when the accident occurred, the Uganda Police Force said in X.
The accident occurred near Chekwatit village in Kapchorwa district, police added.
Preliminary investigations suggested that the driver lost control and the bus went off the road and overturned after hitting a large rock, police said.
Uganda's Minister of Local Government, Balaam Barugahara Ateenyi, said on X that more than 28 children are being treated in hospitals, nine of whom are in critical condition.
Officials have not yet released the names or ages of the children killed. The adult who died is believed to be the school's founder and principal.
Residents arrived ahead of official rescue teams and began pulling victims from the rubble, according to footage released by the Uganda Red Cross Society. Some survivors were brought to hospitals in pickup trucks.
The village where police said the accident occurred is near the Uganda-Kenya border, about 300 km from Kampala.
The government announced the suspension of "all school trips and excursions, with immediate effect and until further notice."
