The family of a Scots jihadi bride said they are full of rage at her actions but questioned new sanctions as she became one of four men and women to face the international restrictions.

The new sanctions, set up in an effort by the Government to stem the flow of Islamic State recruits from the UK, include Aqsa Mahmood, who left her family home in Glasgow in 2013 for Syria.

The former private schoolgirl keeps a blog in which she has published advice for women wanting to travel to join Islamic State and described the Tunisia beach attack which killed 38 people as revenge.

It is the first time the UK has submitted the names of the worst offenders among around 700 thought to have travelled out to the region to join the Islamist extremists.

Approval by a UN committee means the group are subject to a global asset freeze and travel ban, but the move is also designed as a deterrent to dissuade would-be fighters.

Mahmood was added to a UN list along with three others suspected of leading recruitment drives and plotting terror attacks against the UK and elsewhere from strongholds in Syria.

The others are Omar Hussain from High Wycombe, Nasser Muthana from Cardiff, and Sally Jones from Chatham, in Kent.

The family's lawyer Aamer Anwar met with the family after the announcement.

He said: "Aqsa’s family described today’s sanctions as little more than useless grandstanding by the Prime Minister which will have zero impact on the activities of Aqsa Mahmood, but more importantly do very little to deter young people from being recruited to Isis.

"Aqsa’s family remain full of rage at her activities which they describe as a twisted and distorted perversion of Islam, but they had always hoped that one day she would see Isis for the barbaric death cult it is and return home."

He said: "Whilst Aqsa has destroyed any chance of happiness for her own family, they are saddened that the UK Government has failed to take ay genuine steps to win the hearts and minds of other young people on the cusp of radicalisation."

Mahmood is thought to be a key figure in the al-Khanssaa brigade, a female brigade in Raqqa which was established by IS to enforce Sharia law.
