Witnesses have reported that two Tanzanian military armoured vehicles were struck by shells fired by M23 rebels in the Congolese town of Sake.
The incident, which occurred on Thursday, resulted in the injury of one Tanzanian soldier and a civilian, according to a Congolese military source and an eyewitness.
However, the Tanzanian army spokesperson stated that they were not informed of the attack.
Tanzania, along with South Africa and Malawi, deployed troops to the Democratic Republic of Congo (DR Congo) as part of the Southern African Development Community (Sadc) mission. Sadc troops, in collaboration with the Congolese army, have been engaged in clashes with M23 rebels since early February, particularly in the vicinity of Sake. Earlier this month, two South African soldiers were killed in an attack in the same area.
The Sadc intervention followed the withdrawal of the East African Community force, which was ordered by Congolese President Felix Tshisekedi due to perceived inefficiency in combating the M23 insurgency.
In light of the recent escalation in violence, the Congolese army has been advising residents to evacuate Sake. While some have opted to remain, a significant number have fled to the outskirts or to the nearby city of Goma, approximately 25km (15 miles) away.
The United Nations estimates that the recent hostilities have displaced around 215,000 people towards Goma, exacerbating the humanitarian crisis in a region already burdened with a large refugee population.
