The archaeologist Khaled Asaad have been killed by Islamic State (IS) militants. He looked after ancient ruins of Palmyra in Syria and has been taken hostage by the group after it seized the Unesco World Heritage site earlier this year.
The family of the 82-year-old scholar said he had been beheaded by IS fighters, according to Syria's director of antiquities, Maamoun Abdulkarim.
Mr Asaad had spent more than 50 years working on Palmyra.
He was head of antiquities at the ruins, one of the archaeological jewels of the Middle East.
