GCC member states yesterday designated the Fetullah Terrorist Organisation (FETO) group, led by US-based Fetullah Gulen, a "terrorist organisation", stressing their support for the Turkish government.
In their meeting in Riyadh, which was attended by Turkish Foreign Minister Mevlut Cavusoglu, the foreign ministers called for the adoption of new strategies aimed at fighting terrorism emanating from pseudo-religious "cults" such as FETO.
Gulen is also accused of leading a long-running campaign to overthrow the state through the infiltration of state institutions, particularly the military, police and judiciary, forming what is commonly known as the parallel state.
Gulf foreign ministers also stressed their support for Turkey's stability under the leadership of President Recep Tayyip Erdogan.
The announcement also included calls to maintain the fight against Daesh in Iraq, Syria and elsewhere within the context of a 60-nation anti-Daesh coalition led by the US.
