The IHH delivers relief aid to 140 countries worldwide. Quite recently, as a novel humanitarian practice, the IHH has begun acting as a mediator in intra-state conflicts and even accumulated considerable experience in it. In the Bangsamoro peace process, for instance, the IHH was invited to play a mediator role as part of the internationally crewed Third Party Monitoring Team. Similarly, the IHH has been called upon to play mediatory roles in resolving kidnapping incidents in Syria and Pakistan, and has done so by negotiating with armed groups for the release of kidnapped and captive civilians. This paper, therefore, aims to explore the dynamics of and the motivations behind the IHH's extension of its international humanitarian mission beyond providing relief and to examine the place of such civilian mediator role in the broader humanitarian turn in Turkey's contemporary foreign policy.
