A female suicide bomber and another suspected rebel were killed in a blast in Uganda’s capital city.

Two suspected Allied Democratic Forces (ADF) rebels, including a female suicide bomber, were killed in an explosion near a prominent Catholic shrine in Uganda’s capital, Kampala, as crowds gathered to mark Martyrs’ Day.

The blast on Tuesday took place in the upscale suburb of Munyonyo, outside the Munyonyo Martyrs’ Shrine, where Ugandans were assembling to commemorate 19th-century Christians executed for their faith. No civilian injuries were reported.

“A counterterrorism unit this morning intercepted and neutralised two armed terrorists in Munyonyo,” said army spokesman Chris Magezi on X. He confirmed one of the assailants was a female suicide bomber “laden with powerful explosives”.

Footage broadcast by NBS Television, an independent outlet, showed a destroyed motorbike and debris scattered across the road. Police Chief Abas Byakagaba told NBS the explosion occurred while “two people were on a motorcycle,” adding: “The good thing, though, is that there were no people nearby who were injured.”

There has been no immediate claim of responsibility.

While Ugandan authorities are still piecing together the events, Magezi suggested the suspects were linked to the ADF, a rebel group that originated in Uganda in the 1990s but later relocated to eastern Democratic Republic of the Congo.

The ADF has pledged allegiance to ISIL (ISIS) and was behind a spate of deadly bombings in Uganda in 2021.

The group has been accused by the United Nations of widespread atrocities, including the killing of thousands of civilians in the region.

Martyrs’ Day is one of Uganda’s most significant religious holidays, drawing thousands of pilgrims annually. Security forces have increased patrols across the capital in the aftermath of the incident.
