US hostage 'tortured and raped by ISIS leader' speaks from beyond the grave

An American aid worker taken prisoner by ISIS terrorists describes her experiences in a harrowing footage taken before she was killed in an airstrike.
Kayla Mueller was forced to marry ISIS leader Abu Bakr al-Baghdadi , and was reportedly tortured and constantly raped before her death last year.
In the proof of life video, which was made by ISIS and sent to her parents, who have just released it to ABC , she says:

"My name is Kayla Mueller. I need your help." "I've been here too long, and I've been very sick. It's, it's very terrifying here," she said to the camera before the footage abruptly stopped.

 The .mp4 video clip was only 10 seconds.The video is believed to be the only footage of her in captivity.Her father Carl described the moment he saw it. He said:

"You just go into almost a catatonic state, I think. You can't even stand up."

Her mother Marsha added:

 "I saw how thin she looked, I saw her eyes were clear. She was very steady so it broke my heart.But I also saw her strength."

The 26-year-old was held captive at the home of al-Baghdadi's deputy Abu Sayaff.The Islamic State’s second in command was allegedly killed alongside Kayla in an air strike on the property near Raqqa, Syria, in February 2015.
She was taken captive in August 2013 in Aleppo, Syria, as she left a Doctors Without Borders hospital.

After graduating from university in 2009, Kayla travelled to northern India, Palestinian territories and Israel to assist humanitarian groups.
She then went to Syria to help people whose lives had been torn apart by war, concentrating on children.
There she was kidnapped by jihadis in August 2013 following a short visit over the border from her base in Turkey.

It is believed ISIS were tipped of about her presence by a spy who informed she was there with her Syrian photographer boyfriend Omar Alkhani.
He was later released.
