Uganda's military said on Thursday it had discovered bomb making material at a training facility for an Islamic State-allied rebel group around 60 kilometres west of the capital Kampala, and that three people had been detained.
Authorities blamed the Allied Democratic Forces (ADF), a militia based in the dense forests in neighbouring Democratic Republic of Congo, for a series of bombings in Kampala and elsewhere late last year which left at least nine people dead.
In one of the worst attacks, a suicide bomber blew himself up at the entrance of a police station in the centre of Kampala. Three minutes later two other suicide bombers detonated along a road that leads to the parliament.
