ABUJA - Pirates boarded a ship two days ago off the coast of Nigeria's oil-region, a piracy watchdog said on Tuesday, the latest in a string of attacks close to Africa's biggest energy producer.
The attack took place around 55 miles off the coast of the Brass oil region on Sunday, the International Maritime Bureau (IMB) said in a piracy report.
There were reports that an unknown number of foreigners were kidnapped in the attack on the Armadah Tuah vessel, according to maritime-risk exports AKE.
The Nigerian navy did not respond to requests for comment.
"If confirmed, the attack would be the third offshore kidnapping in the area in 10 days, following the attacks on Esther C and Walvis 7 on Feb. 7 and Feb. 10 respectively," AKE said in a security report.
In a separate attack on Sunday, robbers in a wooden boat boarded a ship anchored at the Lagos port and stole the stores kept on the ship before escaping, the IMB report said.
