At least 16 people drowned, including four children, when a rubber boat carrying migrants sank off Turkey's northwest province of Canakkale, the state-run Anadolu news agency reported on Friday.
Canakkale's Governor Ilhami Aktas told Anadolu that four migrants were rescued and admitted to hospital.
Search and rescue operations have continued, involving ten coastguard boats, two helicopters, marine police, Turkey's Disaster Management Authority (AFAD) and National Medical Rescue Team (UMKE).
It was not immediately clear how many migrants were on the boat, the governor added.
