The news that Charlie had died on Friday afternoon led to an outpouring of grief from well-wishers around the world.

The 11-month-old baby suffered from an extremely rare genetic condition causing progressive brain damage and muscle weakness, and his parents' long struggle to save him drew an international outpouring of sympathy.

"Our beautiful little boy has gone, we are so proud of you Charlie," said Connie Yates, the baby's mother.

Following news of Charlie's death, US Vice President Mike Pence tweeted: "Saddened to hear of the passing of Charlie Gard. Karen & I offer our prayers & condolences to his loving parents during this difficult time."
