Lebanese police have arrested a man in connection with the killing of a British embassy worker in Beirut.
Rebecca Dykes' body was found at the side of a motorway in the east of the capital, police said.
An official said the suspect confessed that he killed Ms Dykes and that the murder was a "criminal act" and not politically motivated.
According to reports Ms Dykes had been at a colleague's leaving party in the Gemmayzeh district of Beirut on Friday night.
She was working as a programme and policy manager with the Department for International Development and as policy manager with the Libya team at the Foreign Office (FCO), according to her LinkedIn page.
She had previously worked as an Iraq Research Analyst with the FCO.
British Ambassador to Lebanon Hugo Shorter tweeted that everyone at the embassy was "deeply shocked, saddened by this 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.

Ms Dykes, a University of Manchester graduate, also had a Masters in International Security and Global Governance from Birkbeck, University of London.
A Department for International Development spokesman said: "Our thoughts are with Becky's family and friends at this very upsetting time.
"There is now a police investigation and the FCO is providing consular support to Becky's family and working with the local authorities."
