KOCAELI, Turkey

A far-left terror suspect was arrested in northwestern Turkey as part of a counter-terrorism operation, a security source said on Thursday.

The wanted suspect, whose identity was not revealed, was arrested in an operation conducted by a counter-terrorism squad of the police in Kocaeli province, said the source who asked not to be named due to restrictions on speaking to the media.

Digital materials and documents related to the DHKP-C terror group were also seized during the operation.

The DHKP-C is responsible for a number of terror attacks in Turkey, including a 2013 attack on the US Embassy in Ankara, which martyred a Turkish security guard.

The group is listed as a terrorist organization by Turkey, the US, and the EU.
