The family of a British woman who fled to join Islamic State in Syria have said they are 'sickened' by a poem she wrote praising the massacre in Tunisia and attacks in Kuwait and France.

Former private schoolgirl Aqsa Mahmood left her home in Glasgow in November 2013 and married a militant from the terror group in February last year.

She has since posted a series of radical messages under the nom de guerre Umm Layth, including a call for others to copy the murder of soldier Lee Rigby and the Boston Marathon bombing.

In her most recent blog post, the 20-year-old celebrated Friday's terror strikes as 'revenge' and 'a day that will go down in history'.

Her family have today condemned the poem, describing it as 'twisted and evil' and saying there was 'no glory' and 'no god' at work in the 'cowardly' strikes. Above, her parents, Muzaffar and Khalida Mahmood last year

It emerged in the wake of the shooting at the Tunisian beach resort which left 38 tourists - including 18 Britons - dead, the suicide bombing at a mosque in Kuwait and the beheading in France.

The poem read: 'In 3 different locations a family was born. It's name was change, freedom and revenge.'

It continued: 'Kuwait, France and Tunisia is where they reside. They left a mark which will always remain. Permanent and blunt.'

Her family have today condemned the poem, describing it as 'twisted and evil' and saying there was 'no glory' and 'no god' at work in the 'cowardly' strikes.

A statement released by their lawyer said: 'The family of Aqsa Mahmood became aware yesterday of her blog Umm Layth posting praise for the attacks in Tunisia, France and Kuwait.

'They are full of rage at her latest diatribe masquerading as Islam during the holy month of Ramadan.

'Whilst their daughter may have destroyed any chance of happiness for her own family, they are sickened that she now celebrates the heartbreak of other families.

'The Mahmood family have a message for any young person attracted to Isis, they say there is no honour, no glory, no god at work in the cowardly massacre of holidaymakers, people at prayer in a Shia mosque or an innocent man at his place of work.'

It added: 'As for Aqsa's words they can only be described as twisted and evil, this is not the daughter that they raised.
