The Nigerian Navy has said it would investigate the attack by suspected pirates on a Turkish cargo ship off the coast of Nigeria.
The Navy spokesman Commodore David Nabaida told reporters late on Friday in Abuja.
Suspected pirates were said to have attacked a Turkish cargo ship off the coast of Nigeria, injuring three crew members.
Between eight and 10 suspected pirates with automatic weapons were reported to have boarded the ship late on Thursday.
They were said to have robbed the crew of money and cell phones, but fled when the ship's captain began making distress calls.
