A UK military team consisting of around 12 personnel has been deployed to support the ongoing UN peacekeeping mission in South Sudan.
The team will assess how the UK can provide support as part of a wider contribution to the UN Mission in South Sudan (UNMISS).
UK Defence Secretary Michael Fallon said: "This is another demonstration of the flexibility and global reach of our Armed Forces.
"It will support UN efforts to end some of the world's most destabilising conflicts, helping to tackle a key driver of migration."
Additional troops will be deployed following an initial scoping assessment. The troops may be sent to conduct specific tasks, such as providing vital engineering work to strengthen infrastructure, and offering further advisory support.
The number of personnel to be sent is yet to be finalised. A total of 250 to 300 troops could participate in South Sudan over the course of multiple deployments, and up to 70 personnel could be deployed to Somalia.
Since conflict began in December 2013, millions of people have been displaced and faced food shortages.
The UK is said to have allocated more than £260m to resolve the humanitarian crisis in South Sudan.
In September, UK Prime Minister David Cameron announced that the country will double its contribution to active peacekeeping this year.
