The US had announced a humanitarian truce between Kinshasa and the M23 rebel group on July 5.
Two children and two teenagers have been killed in a bombardment in the Democratic Republic of Congo (DRC), local sources have told AFP news agency.
The United States announced a humanitarian truce on July 5 between Kinshasa and the M23 rebel group operating in eastern DRC. It was supposed to last until July 19, but fighting erupted on Friday.
A spokesman for one of the armed groups backing the DRC forces said the fighting occurred 70km (43 miles) northwest of the North Kivu provincial capital, Goma.
By Monday, the fighting had reached the town of Bweremana, around 15km (9.3 miles) west of Goma, where the deadly bombardment struck.
The dead included two children from the same family, according to Innocent Mwitehofu Mumbara, a local civil society leader. The four victims were aged two, three, 16 and 18, Mumbara added.
A mother and her four-year-old child were among the wounded, said Bweremana Police Commissioner Paulin Ilunga, claiming that the shell had “come from the hills where the M23 is”.
Confirming the deaths of four people in the attack, a hospital source told AFP that five more had been admitted with serious injuries.
The DRC has been facing political instability and armed violence since 1996, with an estimated six million people killed since the conflict began.
Since the end of 2021, the M23, supported by units of the Rwandan army, had seized vast swathes of territory in North Kivu, going so far as to almost completely encircle Goma.
According to a Human Rights Watch report, M23 allegedly executed scores of villagers and militia members between November 2022 and April 2023, burying them in mass graves in the village of Kishishe, North Kivu.
The report says that M23 has committed unlawful killings, rape, and other war crimes since late 2022, exacerbating the dire humanitarian crisis in the country. A total 171 civilians were executed in the last 10 days of November alone, according to the UN Human Rights Office.
At the end of June, the M23 and the Rwandan army seized several towns in Lubero territory, in the north of North Kivu, following the collapse of the Congolese army and its auxiliary militias.
Nearly 50 soldiers were sentenced to death in the following days for “fleeing the enemy”.
