Alan Henning’s daughter found out about his murder after seeing photos on Instagram, she has revealed.
Lucy Henning stumbled across gruesome pictures on the social media app just after her father’s death at the hands of the so-called Islamic State (also known as Isis, Isil or Daesh), the Press Association reported.
The 18-year-old had hoped that the terror group would release her father, a taxi driver from Salford, who had gone to Syria to help deliver aid.
Speaking on The Jeremy Kyle Show, in an episode titled 'My dad was executed by Isis’, the teenager said: "I remember thinking we have had a few days, no news, it's looking good. We thought they might actually let him go.
"Then I remember I was just laying in bed on Instagram and er, I just saw the final picture. It was the final picture, after the execution.
"You just kind of go through in your head, like whenever I used to get upset about it, I used to torture myself thinking, 'You don't know what he's going through,' so how can you sit there crying.
"So I used to just shout at myself, you can't cry, you can't be upset, think about what he's going through, think about what everybody else is going through."
Henning said that she did her best not to think about the terrorists who murdered her father.
She said: I try not to think about them. I think I'm still numb. I just try and get everyone to remember like, the kids that are still there, when people say, 'Oh you've lost your dad,' Yeah I know but there's kids there that's lost, lose all their family in one day and they are stuck there on their own."
She added that she is herself looking to do voluntary work in Africa and hopes to make a visit in memory of her father to the region.
"There's an academy that's been set up in my dad's name, the Alan Henning Academy, for Syrian children, just on the Turkey side, and it's schooling around 400 pupils at the moment, getting them the education they need, so I would like to go and visit," she added.
The news comes after it was announced that US officials believe "with a high degree of certainty" that they have killed Alan Henning’s suspected murderer in a drone strike.
Briton Mohammed Emwazi, nicknamed Jihadi John, appeared in video in which he appeared to murder Henning, as well as American journalists James Foley and Steven Sotloff, and British aid worker David Haines. He was also implicated in the murder of American aid worker Peter Kassig and Japanese journalist Kenji Goto.
