Police in southern Turkey's Adana arrested Sunday four Daesh-linked suspects, according to security sources.

The suspects were arrested at dawn, confirmed one source who asked not to be named due to security concerns.

The detained are Syrian nationals. They entered Turkey through the Syria border and were plotting a terrorist attack in the southern province.

Since recognizing Daesh as a terrorist group in 2013, Turkey has faced several Daesh attacks, including 10 suicide bombings, seven bombings and four armed attacks, killing 315 people and injuring hundreds.

In response to the attacks, Turkey launched counterterrorism operations at home and Syria, neutralizing 3,500 Daesh terrorists and arresting 5,500.
