Authorities in the Democratic Republic of Congo’s eastern city of Beni on Sunday declared a curfew following two bomb blasts in a day.

"I don't want to see anyone in the street," the mayor of the city, Col Narcisse Muteba, said, warning there was information that more attacks were being planned.

In the latest incident a person carrying a bomb died when it detonated outside a bar.

Earlier on Sunday at least two people were injured when a makeshift bomb exploded inside a Roman Catholic Church in the same city.

It happened shortly before a children's confirmation ceremony was due to begin.

Although it's not yet known who was behind the blasts, a rebel group called the Allied Defence Forces - or ADF - carries out frequent attacks in the region and has targeted churches before.

In May, two imams known for speaking out against ADF violence were shot dead - one of them inside a mosque.
