Britain’s Foreign and Commonwealth Office (FCO) advise against all travel to Somalia, including Somaliland.

The Foreign and Commonwealth Office (FCO) advise against all travel to Somalia, including Somaliland. Any British nationals in Somalia should leave. There is a high threat from terrorism, including kidnapping, throughout Somalia, including Somaliland. Terrorist groups have made threats against westerners and those working for western organisations. The FCO believes that there is a constant threat of terrorist attack in Mogadishu. The FCO also believes that terrorists continue to plan attacks against westerners in Somaliland.
Terrorist attacks could be indiscriminate, including in crowded places, high-profile events, events involving government officials and in places frequented by foreigners. See Terrorism.
Piracy is a significant threat in the Gulf of Aden and Indian Ocean. There is also a high threat of maritime terrorism in the territorial and international waters off Somalia. See Sea travel.
All areas across Somalia are suffering food shortages resulting in the displacement of thousands of Somali people. See Local Travel.
The FCO is unable to provide consular assistance in Somalia. See British representation. Take out comprehensive travel and medical insurance before you travel.
