UK Armed Forces personnel have been deployed to South Sudan to support the UN peacekeeping mission.
South Sudan gained its independence in 2011.
The United Nations Mission in the Republic of South Sudan (UNMISS) focuses on the protection of civilians, monitor human rights and support implementation of the cessation of hostilities agreement.
The deployment is in line with UK Prime Minister David Cameron's announcement last year that the UK would send up to 300 troops to South Sudan and around 70 to Somalia this year to support active peacekeeping.
The small military team will be joined by further deployments throughout this year.
UK Defence Secretary Michael Fallon said: "The arrival of British personnel clearly demonstrates our commitment to supporting UN efforts to improve conditions in some of the world's most destabilising conflicts."
The British troops will be divided into two engineer squadron groups, with associated support elements.
The personnel will provide advisory support and vital engineering work to strengthen infrastructure for the UNMISS.
The first UK military personnel have also arrived in Somalia, following the initial deployment last month.
Besides South Sudan and Somalia, UK troops also carry out peacekeeping support in several other countries.
