A memorial service is being held for a British man, murdered by Islamic State militants.
Alan Henning was volunteering as an aid worker in Syria last December when he was taken hostage.
A video showing his beheading was posted online in October.
His widow Barbara has paid tribute to her husband at the service in Eccles in Greater Manchester:
A video was posted on October 3 showing Mr Henning being beheaded by IS, just weeks after fellow British aid worker David Haines was also murdered by the terror group.
More than 400 friends and family were at Eccles Parish Church, including Mr Haines' daughter Bethany and brother Michael.
Yellow ribbons lined the town centre and the churchyard in memory of Alan and many of the congregation wore yellow scarves and ties. Later, a memorial stone will be unveiled in Mr Henning's honour.
Mrs Henning told the mourners: "We will never forget Alan but we must also never forget the reason why he went to Syria and the way he was taken from us for being what we should all be - selfless and caring.
"My thoughts are with the families of James Foley, Steven Sotloff, David Haines and Peter Kassig and I hope and pray that James Cantlie will be released and returned to his family so they are spare the horror."
Mrs Henning said she and her family had been devastated by the "senseless act of barbarity" and that children Lucy and Adam may never understand the murder of their "loving, funny and amazing dad".
She said: "Alan was a peaceful, selfless man who left his family in the UK at Christmas 2013 to drive in a convoy all the way to Syria with his Muslim colleagues and friends to help those most in need. We, as a family, are extremely proud of him.
"Lucy and Adam understood why he had to go, he had explained to them how he had seen children with nothing, living in tents and queuing for food and water, and how much harder it was for them in the middle of winter."
Also speaking at the memorial, Lucy, 17, said: "We saw what he was like when he came back from Syria and how touched he was by what he did. He was happy.
"We shared our dad with the children of Syria and I'm glad we did."
Meanwhile, funds have been set up in Mr Henning's memory, raising more than £30,000 and Prime Minister David Cameron has said he will consider a bid by Mr Henning's local MP to have the aid worker recognised with a national honour.
A previous memorial service was held for Mr Henning last month at the British Muslim Heritage Centre in Manchester and Mrs Henning and her children also travelled to Scotland to show their support for David Haines' family at the service held in his memory.
