BEIRUT: The baby son of Shamima Begum, a British-born teenager who left London to join the Daesh extremist group, has died in Syria, the US-backed Syrian Democratic Forces said Friday.
Begum, 19, who was stripped of her citizenship by the British government despite her wish to return, gave birth last month in a refugee camp in northeast Syria.
The baby died of pneumonia, according to a medical certificate, the BBC reported.
She had previously given birth to two other children who are said to have died, apparently from illness and malnutrition.
SDF spokesman Mustefa Bali confirmed the death to AFP but declined to specify how or when it happened. He had previously denied the baby had died in a Twitter post that has since been deleted.
Her case has highlighted a dilemma facing many European countries, divided over whether to allow extremists and Daesh sympathisers home to face prosecution or bar them from entry as the so-called Daesh group's "caliphate" crumbles.
The runaway teen, who left East London for Syria when she was 15-years old with two other schoolgirls, said last month she wanted to return to Britain after fleeing fighting between the terror group and US-backed forces.
At the time, Ms Begum told the BBC: "Losing my children the way I lost them, I don't want to lose this baby as well and this is really not a place to raise children, this camp."
But public sentiment hardened against Begum after she showed little remorse about Daesh attacks in media interviews from the refugee camp in eastern Syria.
Home Secretary Sajid Javid revoked her citizenship, deeming her a security risk, although the government had hinted her newborn son could be treated differently.
After news of the baby boy's death emerged, senior opposition figure Diane Abbott criticised the government's decision.
"It is against international law to make someone stateless, and now an innocent child has died as a result of a British woman being stripped of her citizenship," she tweeted.
"This is callous and inhumane."
A mass exodus from the jihadists' last redoubt in eastern Syria has sparked a humanitarian emergency, as the SDF leads an offensive to smash the last remnants of the Daesh territory.
The International Rescue Committee on Friday said that 12,000 women and children had arrived at the Kurdish-run Al Hol camp since Wednesday.
Since December, at least 100 people have died en route to the camp or shortly after arriving, mostly children under five, the IRC said.
