IS bride Shamima Begum would “face the death penalty” for terrorism if she came to Bangladesh, the country’s foreign minister has said.
Abdul Momen told the BBC that Ms Begum has “nothing to do” with his country.
The 19-year-old, who left east London to join the Islamic State group in 2015, was stripped of her British citizenship in February.
Her claim to Bangladeshi nationality through her mother is believed to have informed the Home Office’s decision.
Under international law, it is illegal to deprive a person of citizenship if to do so would leave them stateless.
Ms Begum’s lawyer, Tasnime Akunjee, said “in no way is she Bangladesh’s problem”.
Ms Begum is appealing against the Home Office’s decision.
Mr Momen said there was “no question” of giving Ms Begum Bangladeshi citizenship or allowing her into the country, piling pressure on Home Secretary Sajid Javid to settle her status.
“She has never sought Bangladeshi citizenship and her parents are also British citizens,” he told the BBC.
“The British government is responsible for her. They’ll have to deal with her.”
He added that, if she did end up coming to Bangladesh, she would fall foul of the country’s “zero tolerance policy” towards terrorism.
“Bangladeshi law is very clear. Terrorists will have to face the death penalty,” he said.
Although Ms Begum travelled to Syria to join the IS group, she has not admitted any terror offences.
