A blonde Danish teenager who murdered her mother after watching ISIS' sickening filmed beheadings of British hostages has been jailed along with her older jihadi lover.

Lisa Borch was aged only 15 when in October last year she spent hours on YouTube watching footage of the savage decapitations of David Haines and Alan Henning.

Afterwards she and her radical Muslim boyfriend Bakhtiar Mohammed Abdulla, 29, took a long-bladed kitchen knife and stabbed her mother Tina Römer Holtegaard at least 20 times at the home they shared in rural Kvissel.

A court which sentenced Borch to nine years in jail heard how she became obsessed with militant Islam after falling in love with an unnamed Muslim man.

But he jilted her when he moved back to Sweden to be with his wife and children
