Pirates attacked a Greek-owned oil tanker off Nigeria Friday but failed to hijack the ship after the crew hid in a safe room, the International Maritime Bureau said.
The tanker was anchored off Lagos when armed pirates boarded early on Friday, said Noel Choong, head of the IMB's piracy reporting centre in Kuala Lumpur.
The 23 crew onboard managed to lock themselves into a safe room and sent out a distress call that was received by the IMB, which in turn alerted the Nigerian navy and other warships patrolling the area, Choong said.
Safe rooms are increasingly used by shipping firms to protect crews and thwart pirate attacks.
Choong said the pirates, likely aiming to steal the ship's cargo, abandoned their plan as they could not enter the safe room and urged crews of other ships off West Africa to be vigilant.
"The area remains risky. We urge all ships to maintain strict anti-piracy watches," he told AFP news agency.
