ANKARA

At least seven people trying to cross illegally from Turkey to Greece, and from Syria to Turkey were caught by Turkish border units, the country's National Defense Ministry said on Monday.

The ministry tweeted that four of the held persons were members of the Daesh/ISIS terrorist group, and another two belonged to the Fetullah Terrorist Organization (FETO).

FETO and its US-based leader Fetullah Gulen orchestrated the defeated coup of July 15, 2016, which left 251 people killed and 2,734 injured.

Ankara accuses FETO of being behind a long-running campaign to overthrow the state through the infiltration of Turkish institutions, particularly the military, police, and judiciary.

Turkey was one of the first countries to declare Daesh/ISIS a terror group.

The country has since been attacked by the organization multiple times. It has carried out at least 10 suicide bombings, seven bomb attacks, and four armed attacks, killing 315 people and injuring hundreds more.

In response, Turkey launched anti-terror operations at home and abroad to prevent further attacks.
