(CNN) The newborn son of British ISIS bride Shamima Begum has died, the Kurdish Red Crescent confirmed to CNN.

Begum, who left east London to join ISIS in Syria when she was 15, made international headlines last month as she publicly pleaded with the UK government to be allowed to return. She was 19 when she gave birth to her baby, Jarrah, in a Syrian refugee camp in February.

After the baby's health deteriorated on Thursday, medical staff from the Kurdish Red Crescent transferred the mother and baby from al-Hawl camp to the main hospital in al-Hasakah City in northern Syria. The baby died a few hours after arriving at the hospital, the NGO said.

Her son's death comes after UK Home Secretary Sajid Javid decided to revoke her British citizenship.

In response to the news, a British government spokesperson told CNN that "the death of any child is tragic and deeply distressing for the family."
