A wave of attacks on villages in eastern DR Congo attributed to Islamic State-affiliated ADF rebels killed at least 15 people Sunday, local officials said.

These latest killings come a week after a similar attack left more than 20 dead.

A humanitarian source confirmed seven fatalities in Manyala and "at least eight" in Ofay.

ADF fighters were also blamed for last weeks raids in the neighboring province of North Kivu cost at least 23 lives while in the same province at least 14 people were killed in a bomb blast at a Pentecostal church.

Islamic State portrays the ADF, which has its roots in Rwanda, as its central African incarnation.

In an attempt to stem the violence the government in May 2021 declared a state of alert in North Kivu and Ituri, replacing civil administrators with police and troops.
