White House confirms death of Kayla Mueller
The US has confirmed the death of aid worker Kayla Mueller, who had been held hostage by Islamic State (IS) militants in Syria.
Her family said they were "heartbroken" to learn the news, and released a letter written during her captivity.
Last week, Islamic State said she had died in a Jordanian air strike, without providing proof.
