(Reuters) - One of three schoolgirls who left London in February of 2015 to join Islamic State has died, her family lawyer told Reuters on Thursday.

Attorney Tasnime Akunjee said the family of Kadiza Sultana learned of her death in Raqqa a few weeks ago.

The BBC said she was believed to have been killed in an air strike in Syria.

Sultana, 16, along with two other friends, flew from London's Gatwick Airport to Turkey on Feb. 17, 2015.

The British Home office and British Interior Ministry could not be immediately reached for a comment.
