The Bosporus was closed for navigation due to an incident with the Liberian-flagged Songa Iridium cargo ship.
The cargo ship heading from Odessa to Istanbul collided with shore, according to the NTV Channel.
"Songra Iridium, with 19 crew and a guiding pilot captain, sent out a signal of mechanical failure at 12:00 (4am ET) and hit the shore near the Rumelihisar district at 12:13 (4:13 am ET)," CNN cited the statement as saying.
There were no immediate reports of casualties. The cause of the incident is under investigation.
