Three Tanzanian soldiers have been killed by mortar fire in the eastern Democratic Republic of Congo.
The troops were part of a Southern Africa force deployment to assist government troops battling M23 rebels.
The regional force sent soldiers to North Kivu province in December to help Kinshasa regain ground from the M23 militia.
The force combines regional military heavyweight from South Africa, Tanzania and Malawi.
“This unfortunate incident happened after a hostile mortar round had fallen near the camp (where) they were staying,” the 10-nation Southern African Development Community (SADC) said in a statement.
A source close to the government in North Kivu said the mortar attack struck last Thursday and a ceremony to honour the dead was held at SADC headquarters in the provincial capital Goma on Monday.
A South African soldier has also died in hospital while being treated for health related issues, the SADC statement said.
After several years of dormancy, the mostly-Tutsi M23 (March 23 Movement) group took up arms again in late 2021 and seized vast swathes of North Kivu province.
