The children died at Runyanya Primary School in the Kiyandongo district, about 189 kilometers (117 miles) northwest of the capital, Kampala, the newspaper said. They were waiting in their classroom for a storm to pass when the lightning struck, it said.
The deaths came as at least 37 children and two teachers were wounded in another lightning strike at a school in Paidha near the Congolese border, the newspaper said.
In the past “few weeks,” at least 40 people have died in Uganda after being hit by lightning, the newspaper said.
