CBS News correspondent Sheila MacVicar is aboard the Canadian warship HMCS Winnipeg, which first responded to a distress call by a Lebanese flagged cargo ship called the Maria K. The crew reported rocket propelled grenade fire from the pirates.
Within minutes, three naval helicopters from the Winnipeg were in the air and on their way to the Maria K, located about 60 miles away. The pirates broke off their pursuit of the Maria K and headed instead for the nearby American ship.
An Italian Naval helicopter joined the Canadian aircraft. With the helicopters hovering overhead, the pirates gave up their attempted hijacking and threw their weapons overboard before their boat was boarded by Italian seamen.
The craft was approximately .75 nautical miles from the U.S. ship before turning away, according to Maersk Lines, Limited, based in Virginia.
Maersk Lines said the Maersk Virginia was not fired upon and that all crewmembers are safe.
"Maersk Lines, Limited continues to evolve security measures aboard its ships transiting the Gulf of Aden and Western Indian Ocean. The company is committed to ensuring the safety of its crew," Maersk said in a statement.
The Gulf of Aden is infested with Somali pirates, but is a crucial shipping channel for hundreds of merchant vessels every day. An increasing number of international warships have been moved to the region to protect them.
Maersk Virginia Captain Sean Hughes went through a similar ordeal in the Gulf of Aden in November 2008, when pirates chased him as he piloted the same vessel to safety by out-maneuvering the bandits.
