A Canadian warship on Sunday thwarted a pirate attack on a merchant vessel in the Arabian Sea, the military said in a statement.
HMCS Winnipeg was deployed in the NATO led counter-piracy mission Operation Allied Protector, escorting ships in the region, when it spotted "several small skiffs" nearing the Motor Vessel Pacific Opal.
The Pacific Opal radioed for help.
A navy helicopter was immediately dispatched and put itself between the Pacific Opal and the pirate skiffs, forcing them to withdraw, said the warship's commander.
