One person was killed and three others were injured in a bomb explosion in Uganda’s capital, Kampala.
The blast went off on Saturday night at a bar, killing a 20-year-old waitress and scattering panicked revelers on to the street outside.
Police say three suspected bombers disguised themselves as customers and planted explosives in a plastic bag.
The president described the event as “a terrorist act”.
The explosion comes one week after the UK government issued an alert about terrorism in Uganda.
It warned British citizens in the East African country. It advised them to be vigilant at public places, including restaurants and bars.
Police have cordoned off the scene of the blast – a venue popular for roasted pork and beer, in a largely residential area on the city outskirts.
Police spokesman Fred Enanga said the suspected bombers ordered food and drinks at the bar, before placing the bag under a table. The explosion went off moments after they left.
Investigators have found nails, ball bearings and other metal fragments, Mr Enanga added, suggesting the explosion was caused by an improvised explosive device.
Uganda’s President Loweri Museveni said on Twitter that the blast seemed to be a terrorist act and promised to catch the perpetrators.
“The public should not fear, we shall defeat this criminality like we have defeated all the other criminality committed by the pigs who don’t respect life,” he said.
