During a telephone conversation on Tuesday, Turkish Foreign Minister
Mevlut Cavusoglu told US Secretary of State John Kerry that “both Turkey and Russia know the Gulenist Terror Cult (FETO) was behind Russian envoy Karlov’s assassination,” according to Daily Sabah.
Gulen, the 74-year-old cleric, was a popular preacher and former imam
before starting his own movement. He was a staunch ally of Erdogan when
the Turkish leader was rising to power, but the two fell out and have
become bitter rivals.
