Barack Obama, the US president, has confirmed the death of a US hostage held by the Islamic State of Iraq and the Levant (ISIL).
The White House issued a statement on Tuesday confirming the death of Kayla Mueller, who had been reported killed in an air strike against ISIL positions carried out by the Jordanian military on Friday.
"No matter how long it takes, the United States will find and bring to justice the terrorists who are responsible for Kayla's captivity and death," Obama said in a statement on Tuesday.
