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 under way.
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.
Hugo Shorter, the British Ambassador to Lebanon, tweeted that the whole embassy was "deeply shocked" and "saddened" by the news.
The whole embassy is deeply shocked, saddened by this news. My thoughts are with Becky’s family, friends and colleagues for their tragic loss. We're providing consular support to her family & working very closely with Lebanese authorities who are conducting police investigation.
