US officials promise to hold terrorists to account after capture of 'IS Beatles'

United States officials have pledged to hold terrorists accountable following the capture of two Britons suspected of having been part of the Islamic State extremist group dubbed "The Beatles".

Alexanda Kotey and El Shafee Elsheikh are currently being held in Syria after their capture by Kurdish militia fighters in January and a US Department of Defence (DoD) spokesman said they are "still considering options" for the pair.
