Uganda’s President Yoweri Museveni says "neither rural-based insurgency nor urban terrorism" will succeed, following two separate bomb attacks this month.

In a televised national address, he referred to the perpetrators as opportunists and parasites attacking unarmed civilians.

The Democratic Republic of Congo-based militant group Allied Democratic Forces (ADF), which now calls itself the Central African Province of Islamic State, has been blamed for the two attacks.

The Islamic State-linked group said it carried out the Saturday attack in the capital, Kampala, which killed a waitress and injured three other people at an eatery.

Another explosion went off in a bus heading from the capital to west of the country on Monday. Police said it killed only the suicide bomber, who was wearing the device.

The ADF have a history of urban attacks, and according to Mr Museveni, planted at least 30 bombs within Kampala between 1997 and 2001, killing more than 120 people.

They are also accused of killing several high profile political and security figures, and at least eight Muslim clerics across the country since 2012.

President Museveni said six ADF operatives had been killed and more than 30 others arrested in relation to these incidents.
