A man who hijacked a passenger ferry has been killed by Turkish special forces.
It is thought the assailant may have had links to militant Kurdish separatists.
The Governor of Istanbul said explosives were found on the dead man.
The vessel had been hijacked in the Sea of Marmara in northwest Turkey after it left the port of Izmit on Friday afternoon. Around 20 passengers were on board.
The high-speed sea bus then ran out of fuel and had to anchor west of Istanbul.
Earlier reports had suggested that four or five hijackers were involved.
The authorities say none of the passengers were hurt during the rescue operation and the members of the crew are all safe.
They are now trying to identify the dead hijacker.
