The bulk carrier Delight was hijacked by Somali pirates in the Gulf of Aden on Tuesday, the latest raid in the Horn of Africa's perilous waters.
A spokesman for the International Maritime Bureau Piracy Reporting Centre in Kuala Lumpur said coalition naval forces were 'monitoring the hijacked ship at the moment'.
The coalition established a maritime security patrol area around the Gulf, one of the world's busiest shipping lanes, in August.
In October, Nato ships joined the international naval effort, which also includes the European Union.
The Delight, with 25 crew, was captured off the Yemen coast on Wednesday and was headed for Somalia, an official at Hong Kong's Maritime Rescue Coordination Centre told Reuters.
Hong Kong's marine department said the ship remained in pirate hands, but communications with the captured crew were still possible.
'The marine department is liaising closely with the manager of the ship ... we are still trying to check the latest situation onboard the ship', a Marine Department spokesman said while declining to give details on ransom or other demands. -- REUTERS
