The daughter of a Scottish aid worker apparently killed by Jihadi John has said she will only feel closure "once there's a bullet between his eyes".
Perth-educated David Haines was beheaded last September after being taken hostage in Syria in March 2013 while working for international relief agency Acted.
The 44-year-old father-of-two had been been helping refugees in a camp near the Turkish border when he was snatched by militants.
His daughter Bethany told ITV News that "it's a good step" that the man in a video of her father's death has been identified in reports as Mohammed Emwazi, but that it does not bring any closure.
She said: "It's a good step but I think all the families will feel closure and relief once there's a bullet between his eyes."
Subsequent reports have said Emwazi was known to UK security services before joining Islamic State.
Ms Haines told ITV News: "If they'd known his name earlier they could've stopped him going but they can't and once he's captured I think there will be a lot of happy faces."
She added: "It is shocking but they're doing their job. They're doing the best they can. They've not dealt with a so-called Islamic State like this before. There's no right or wrong.
"There should been more security in airports to stop people doing that and definitely for him, obviously he's part of a terrorist group and is out to kill hundreds of people and it's not right.
"They need to be monitoring airports more clearly. They need to be asking more security questions. Why are people going to Turkey and then getting a connecting flight? It's not right. You don't just go to Syria on holiday."
Ms Haines also raised concerns over the three young girls who have apparently travelled to join Islamic State from London.
Shamima Begum and Amira Abase, 15, and Kadiza Sultana, 16, travelled to Istanbul on 17 February.
Ms Haines told the broadcaster: "One of them is a year younger than me. They've been brainwashed. And it's not their fault but there should've been someone there stopping them."
David Haines, 55, was educated at Perth Academy. A memorial service was held in the town last year.
