ISIS bride Shamima Begum could be hanged for supporting terrorism if she went to Bangladesh, the country's foreign minister has said.

Abdul Momen said his government 'had nothing to do with' Ms Begum, despite Britain's apparent belief that she has Bangladeshi citizenship.

He said the 19-year-old could be arrested if she did go to Bangladesh and warned that the country imposes capital punishment for 'anyone involved with terrorism'.

UK Home Secretary Sajid Javid stripped Ms Begum of her British nationality in February, dismissing her plea to come home from Syria.

Speaking to ITV News, Mr Momen said: 'We have nothing to do with Shamima Begum. She is not a Bangladeshi citizen. She never applied for Bangladesh citizenship.

'If anyone is found to be involved with terrorism, we have a simple rule, there will be capital punishment. And nothing else.'

Describing his country's laws as a 'model in eliminating all terrorists' he said Bangladesh had 'zero tolerance' for ISIS and its allies.

He also blasted the British government for refusing to take in the ISIS bride, saying that his own country would 'open our doors to save humanity'.

Mr Javid used his powers under the British Nationality Act 1981 to strip Ms Begum of her British citizenship.

Such a move is not allowed under international law if it will leave the person stateless.

British officials appear to believe that Ms Begum, who is of Bangladeshi heritage, holds dual citizenship and can therefore have her British nationality removed.

But Bangladesh has repeatedly insisted it has nothing to do with her and Ms Begum is seeking to challenge the decision.

Ms Begum, from Bethnal Green in east London, was 15 when she and two other girls went to join ISIS in Syria in February 2015.

Aged 19 and heavily pregnant, she resurfaced in a refugee camp earlier this year and said she wanted to return to Britain as the self-styled caliphate collapsed.

In an extraordinary interview she admitted she did not regret going to join ISIS, saying the experience had made her 'stronger and tougher'.

She acknowledged she knew the group was carrying out beheadings and executions before she left, adding that she was 'OK with it at first'.

'I had my kids, I did have a good time there. It's just that then things got harder and I couldn't take it any more and I had to leave,' she said.

The weeks-old boy later died in a camp in northern Syria, with reports suggesting he had suffered from breathing difficulties.
