The home secretary is facing criticism after the baby son of Islamic State (IS) bride Shamima Begum died in Syria just weeks after the teenager was stripped of her British citizenship.
Syrian Democratic Forces confirmed on Friday night that the boy, named Jarrah, had passed away two days after being taken to hospital with breathing difficulties.
He was born in mid-February at the refugee camp where his 19-year-old mother has been staying, and had already been unwell in the weeks leading up to his death.
But Shamima who has previously lost two children told Sky News last month that she would not allow him to go to the UK alone as she pleaded to be allowed to return.
The decision by Sajid Javid to strip her of her British citizenship sparked a national debate over whether she should be brought back to Britain.
Following news of the boy’s death, shadow home secretary Diane Abbott branded Mr Javid’s decision as callous and inhumane.
The death of each child is an unacceptable tragedy.
The UK and other countries of origin must take responsibility for their citizens inside North East Syria.
Shamima, from Bethnal Green in east London, was 15 when she and two other schoolgirls ran away from their homes to join IS in February 2015.
She resurfaced heavily pregnant in a refugee camp in northern Syria last month and spoke of her desire to return as the self-styled caliphate collapsed.
Following news of the death of Jarrah who Mr Javid had said was a British citizen a government spokesman said: The death of any child is tragic and deeply distressing for the family.
The Foreign and Commonwealth Office has consistently advised against travel to Syria since April 2011.
The government will continue to do whatever we can to prevent people from being drawn into terrorism and travelling to dangerous conflict zones.
Mr Javid had insisted that Shamima would not be left stateless because of his decision, amid speculation that she is a dual British-Bangladeshi national.
After the Bangladeshi government claimed she was not a Bangladeshi citizen, Shamima told Sky News that she had no desire to go to the country.
She said: I don’t have anything there, another language, I have never even seen the place, I don’t know why people are offering that to me.
