KINSHASA - The United Nations and Tanzania have opened a joint enquiry into alleged sexual abuse by Tanzanian troops serving in the UN peace mission in the Democratic Republic of Congo, the head of the mission said Saturday.

The UN Stabilization Mission in DR Congo (MONUSCO) ‘Is currently carrying out enquiries concerning several acts of exploitation and abuse implicating members of our Tanzanian contingent’ in the eastern province of North Kivu, said Maman Sambo Sidikou, the UN's special representative in the country.

Under UN rules, the responsibility for investigating and prosecuting peacekeeper sexual abuse lies with the countries that contribute the troops and police to the peace missions. The Tanzanian troops are part of the UN mission's elite intervention brigade deployed at Mavivi, a village near Beni, since September 2015.

A UN team was sent to the area last month on a fact-finding mission.

The United Nations has been rocked by a wave of allegations that its peacekeepers sexually abused civilians in DR Congo and the Central African Republic. ‘Tanzania has sent a team of investigators and we are carrying out a joint enquiry,’ Sidikou told reporters in Kinshasa.

So far 18 cases of sexual abuse have been reported and eight of the victims were minors, said Sidikou. Some of the women have since given birth. Those cases involved a South African, a Malawian and 16 Tanzanian soldiers. Sidikou described the allegations as ‘shocking’ and bringing shame on the United Nations, its force and those involved.
