Investigators have established links between the ADF, a Muslim rebel group that appeared in Uganda but has been rooted for nearly 30 years in the Democratic Republic of the Congo (DRC), and the explosions in a bus Monday near Kampala and in a cafe. from the Ugandan capital on Saturday.

The explosion that left one dead and several injured aboard a bus Monday evening in Lungala, on the road to the DRC, was the result of a suicide attack, Ugandan police said on Tuesday.

“We can confirm that the incident is the result of a suicide attack whose only victim is its perpetrator,” said police spokesman Fred Enanga, pointing out that the 23-year-old suicide bomber was on the list of wanted members of ADF.

Monday’s explosion in Lungala, some 30 km west of Kampala, follows a bomb attack in a Kampala cafe that left one dead – a waitress – and three injured on Saturday night.

The police had considered that this attack came under “internal terrorism” and referred to a “summary” explosive device.

Investigators have now established “a high level of connection” between the two attacks, said Fred Enanga. “The individuals who prepared these explosive devices belong to the same group,” he told a press conference.

Saturday’s attack was claimed by the Islamic State in Central Africa group (Iscap). The IS presents the ADF as its regional branch.

The Iscap had previously claimed responsibility on October 8 for a bomb attack – which had no known victim – against a police station in Kawempe, near where the explosion occurred on Saturday.

The ADF are accused of having killed thousands of civilians in eastern DRC. In March, the United States placed this group on the list of “terrorist organizations” affiliated with ISIS.

The Ugandan police spokesman said that “a number” of ADF activists had been arrested in the country on suspicion of “preparing a plan for a serious attack on important infrastructure”.

“We believe that these militants belonged to sleeper cells in the country, inspired by the ADF in close relation with the IS,” added Fred Enanga in a statement released after his press conference.

Ugandan President Yoweri Museveni for his part linked the suicide bomber who perished Monday to a foiled attack attempt on a national ceremony in August.

“We’ll get them all. Their lousy plans are easy to foil,” Museveni tweeted Tuesday.
