IS victim's daughter says killers deserve 'painful death'
Bethany Haines made the comments after two of the so-called 'Beatles' were captured.
The daughter of IS victim David Haines has said two recently-captured members of the gang which killed him deserve a "slow painful death".
Bethany Haines made the remarks after it was reported that two members of Jihadi John's British execution gang were captured attempting to smuggle themselves into Turkey.
Alexanda Kotey, 34, and El Shafee Elsheikh, 29, both from west London, were believed to be the final two members of the infamous gang still at large, nicknamed "the Beatles" due to their English accents.
Among the group's victims was the British aid worker David Haines, who was taken captive by IS in Syria in 2013.
Mr Haines was beheaded by the terrorist dubbed Jihadi John in September 2014, whose real name was Mohammed Emwazi.
Emwazi, who appeared in propaganda videos showing the execution of British and American hostages, was killed in a British drone strike in 2015.
Mr Haines was the first Briton to die in the killer's videos.

Thousands of Islamic State fighters have sought to flee war-torn Iraq and Syria as the group's foothold in these countries has crumbled.
Ms Haines, 20, from Perth, welcomed the news of the two remaining gang members' capture.
She said: "It's brilliant that these evil people have been caught. The families will now have people to hold account for their loved ones' deaths.
"No punishment is enough for these barbarians and in my opinion they should be sentenced to a slow painful death.
"It's horrible to know that these people will never feel remorse for their crimes but hopefully some justice will be served."
The fourth member of the gang, Aine Davis, is in custody in Turkey where he was convicted on terrorism charges.
Emwazi is also believed to have killed another British captive, Alan Henning, and the American journalists James Foley and Steven Sotloff, while the US government has attributed 27 beheadings to the group.
