The German Navy blog, Marine Forum, reports, 17 August.

“Turkish Coast Guard vessel TCSG-25 (KAAN-15 class) (pictured above) off Istanbul collided with a merchant vessel, capsized … 3 sailors said to be trapped inside … rescue efforts underway”

A later report indicates there are three dead.

In a separate incident, a Turkish Coast Guardsman was killed and a fisherman injured when they attempted to tow a life raft with two bodies aboard near the Syrian boarder.
