British troops to join UN missions in Somalia, South Sudan

London - British troops will join UN peacekeeping missions in Somalia and South Sudan, the government said on Monday.

Prime Minister David Cameron will announce Britain's offer of up to 70 peacekeepers for Somalia and up to 300 in multiple deployments to South Sudan later Monday at the United Nations in New York.

The deployments "will support efforts by the United Nations and African Union to end some of the world's most destabilising conflicts that are prompting mass migration from South Sudan and facilitating the rise of terrorist groups in Somalia", the government said.

"As the world agrees ambitious goals to end extreme poverty, it is absolutely vital that the international community works together to shore up stability in Africa," Cameron said ahead of the UN Peacekeeping Event co-hosted by UN Secretary General Ban Ki-moon and US President Barack Obama.

"Our commitment to peacekeeping operations will help to alleviate serious humanitarian and security issues in Somalia and South Sudan, helping to bring stability to the region and preventing these challenges from spreading further afield," Cameron said.
