UK knows FETÖ behind July 15 defeated coup: Ambassador

The United Kingdom knows the Fetullah Terrorist Organization (FETÖ) is behind last year's defeated coup, according to Britain’s ambassador to Turkey.

Richard Moore told CNN Turk he believes FETÖ and its U.S.-based leader, Fetullah Gülen, orchestrated the failed overthrow attempt that martyred 250 souls and injured nearly 2,200 others.

The U.K. didn not consider the Gulen movement a "terrorist organization" because it required a certain process, Moore said. "But this is not important, we know very well that Gulen movement is behind this coup attempt."

Moore emphasized that Sir Alan Duncan, a senior U.K. Foreign Office minister, was the first overseas official to visit Turkey four days after the defeated coup.

In addition to the botched putsch on Gülen and FETÖ, the terror group is also behind a long-running campaign to overthrow the state through the infiltration of Turkish institutions, particularly the military, police and judiciary.
