The foster carers of the Parsons Green bomber are taking legal action against the council that placed him in their home because he was described as "merely as a troubled young person" when in fact he was "trained to kill by Isis".

Iraqi teenage asylum seeker Ahmed Hassan, who pretended to engage with the anti-terrorism Prevent scheme as he plotted mass murder in London, was sentenced to life with a minimum term of 34 years at the Old Bailey last year.

Hassan's foster parents Penny and Ron Jones, who were awarded an MBE in 2010, are suing Surrey County Council, claiming that the council did not disclose key information about the danger he posed.

The teenager, who lived in Sunbury, Surrey, made a bomb with 400g of "Mother of Satan" explosives and 2.2kg of shrapnel while his unsuspecting foster carers were on holiday in Blackpool.

The bomb injured 51 passengers on September 15 2017.
