At least five people were killed and 15 wounded in a suspected Islamist militant bomb attack during a Sunday service at a Protestant church in the eastern Congolese city of Kasindi, on the border with Uganda, the military said.
An army spokesman said the attack during a Sunday service was likely carried out by the Allied Democratic Forces (ADF), a Ugandan militant group that has pledged allegiance to the Islamic State.
"Despite the security measures put in place, the first indications show that it is the ADF which is behind this bomb attack," Anthony Mualushay said by phone.
The ADF could not be reached for comment. It has not claimed responsibility for the bombing.
"I just came back from the scene, where I saw the bodies of children on the ground," said Kasindi resident Alain Kitsa by phone, describing the atmosphere in the town as tense.
This would be the first time the ADF targeted Kasindi since the group stepped up attacks in the region in 2014, local territorial administrator, Charles Omeonga said, who said the estimated death toll was at least 10.
Kasindi is in a province where Congolese and Ugandan forces have launched a campaign against the ADF, which began as an uprising in Uganda but has been based in Congo since the late 1990s.
