A British woman who worked at the UK embassy in Beirut has been found dead, Lebanese police have said.
Rebecca Dykes' body was found on the side of a motorway on Saturday.
She had been strangled, the BBC was told by senior police sources. An investigation is underway.
Her family said in a statement: "We are devastated by the loss of our beloved Rebecca. We are doing all we can to understand what happened. We request that the media respect our privacy."
Ms Dykes had been working in Beirut as the programme and policy manager for the Department for International Development since January 2017.
Local police say a second post-mortem examination is to be carried out later.
A DfID spokesman said: "Our thoughts are with Becky's family and friends at this very upsetting time."
The Foreign Office said it was in contact with the Lebanese authorities following the death of a British woman in Beirut.
