The authorities in Uganda say a suicide bomber was behind an explosion on a bus in the capital, Kampala, on Monday.
“The attacker died in the explosion,” police spokesman Fred Enanga said on Tuesday.
He added that the attacker was “on a wanted list” and was a member of the Islamist militant group Allied Democratic Forces (ADF), which operates from neighbouring Democratic Republic of Congo.
Several passengers were injured in Monday’s blast.
On Saturday another blast in a restaurant in Kampala killed one person and injured three others.
The police said Saturday’s blast was caused by an explosive device containing nails and pieces of metal, covered by a plastic bag.
Mr Enanga said investigators had established “a high connectivity” between the two attacks.
“There are individuals or groups of individuals preparing these IED [improvised explosive devices] who (belong to) the same group of attackers,” Mr Enanga said.
