Lightning hit Runyanya primary school in Kiryandongo district, about 225km northwest of Kampala, killing 15 girls and three boys yesterday, police spokeswoman Judith Nabakooba said.
"The injured were taken to hospital nearby and 15 of those who were seriously injured were transferred to Mulago hospital," in Kampala, Nabakooba said.
Local media reported that a further 21 pupils were burned after lightning struck at a second school in Zombo district, about 380km north of Kampala. Police could not confirm the incident.
Nabakooba could not provide an exact figure for the total number killed by lightning in recent weeks, but local newspaper The Daily Monitor reported a total of 28 killed and scores injured in the past week, including Tuesday's incidents.
