Pirates attacked a Polish-owned cargo vessel off the Nigerian coast and kidnapped its captain and four crew, Polish authorities said, in the first documented incident of its kind in almost year in some of the deadliest shipping lanes on earth.
The Cyprus-registered Szafir was boarded overnight by armed men in two boats, who looted the 10,000-tonne container ship, operator EuroAfrica said.
The as yet unidentified kidnappers had made no demands so far and Poland was liaising with Nigerian authorities, its Foreign Minister Witold Waszczykowski told a news conference in Warsaw on Friday.
The kidnapped sailors also included other officers, which made the ship impossible to navigate. â€œThe rest of the crew, 11 people, are still on the ship and they are safeâ€¦ The ship suffered some damage,â€ Waszczykowski said.
The ship was anchored around 30 nautical miles (56 km) off the Nigerian coast, and the operator was arranging for a new crew to take it back to port.
Nigerian authorities were not immediately available for comment.
Security experts class the waters off Nigeria as some of the deadliest on earth, with pirates based in the country often targeting oil tankers as well as hostages to ransom.
But the region has seen no documented attacks since February when a crude carrier was boarded, with the shipâ€™s Greek deputy captain killed and three crew members taken hostage.
Polish Maritime Minister Marek Grobarczyk said the safety procedures of all Polish companies operating in the area would be reviewed to ensure sailorsâ€™ safety.
