The baby son of Shamima Begum - who fled London to join the Islamic State group - has died, a spokesman for the Syrian Democratic Forces has said.

The group, which runs the camp where the teenager has been living, confirmed the death on Friday.

The baby died of pneumonia, according to a medical certificate. He was less than three weeks old.

A UK government spokesman said the death of any child was "tragic and deeply distressing for the family".

The spokesman said the government had consistently advised against travelling to Syria and would "continue to do whatever we can to prevent people from being drawn into terrorism and travelling to dangerous conflict zones".

Ms Begum left the UK in 2015 with two friends and was found in a Syrian refugee camp in mid-February. She wanted to return to Britain but was stripped of her citizenship.

Her husband, a Dutch IS fighter called Yago Riedijk, is being held at a nearby prison and has been informed of the baby's death.

A paramedic working for the Kurdish Red Crescent in the camp told the BBC that the baby, called Jarrah, had been suffering from breathing difficulties.

He was taken to a doctor on Thursday morning before being transferred to hospital, along with his mother, but died at 13:30 local time that day, the medical worker added.

Ms Begum has since returned to the camp and her child was buried there yesterday.
