The mother of a US journalist, purportedly seen being killed in a video reported to be by Islamic militants, has said James Foley "gave his life trying to expose the world to the suffering of the Syrian people". In a statement on Facebook, she said:
We have never been prouder of our son Jim.
We implore the kidnappers to spare the lives of the remaining hostages. Like Jim, they are innocents. They have no control over American government policy in Iraq, Syria or anywhere in the world.
We thank Jim for all the joy he gave us. He was an extraordinary son, brother, journalist and person. Please respect our privacy in the days ahead as we mourn and cherish Jim.
