Two of the most wanted fighters from the British ISIS cell called "the Beatles" have called some of the group's actions "regrettable," and insisted that their legal rights are respected wherever they're brought to trial. Alexanda Kotey and El Shafee Elsheikh made the comments during a wide-ranging interview with CNN, which they consented to, from inside a detention facility in northern Syria where they are being held by US-backed Syrian Kurds.
