British Embassy staff in Algeria have been moved to a heavily-guarded hotel because of security concerns.
The embassy building in Algiers has closed and staff are living and working in the Hilton hotel, although some work will be handled from Tunis.
The move follows a security review in the wake of attacks on British targets in Istanbul last November.
It is not believed to be linked to any specific terrorist threat in the north African country.
Jim Currie, Britain's deputy head of mission in Algeria, said: "It is related to the bombing...in Istanbul.
"We took the decision right after that to reinforce our embassy security around the world."
Four bombings at the British consulate, two synagogues and the HSBC bank, killed more than 60 people in the Turkish city in one week.
Hundreds of people were also injured in the suicide attacks, for which 69 people have been charged.
The decision to move the embassy in Algiers comes less than two weeks after four bomb attacks on trains in Madrid which killed 202 people.
On Sunday, Britain's top policeman Sir John Stevens warned that intelligence sharing needed to improve throughout Europe to tackle the threat of terrorism.
Last week he warned that a terrorist attack on London was "inevitable".
Algeria holds its presidential elections in April.
