Pirates are increasingly active in the waters off Somalia, where more than 60 ships have been attacked so far this year resulting in the seizure of over 30 vessels. The East African nation has been without a functioning government since 1991 and has no navy to police its coastline.
"Regular presence in that problem region means the accomplishment of tasks both by separate warships and warship groups from all the fleets to ensure safe shipping in the Gulf of Aden and the Horn of Africa region as a whole," Adm. Vladimir Vysotsky said.
The U.S. Defense Department said on Wednesday that there had been 95 piracy attacks reported in the region this year, 39 of which were successful.
"There are at least 18 ships being held by Somali pirates as we speak," Pentagon spokesman Geoff Morrell said. "I believe our count is that 330 mariners are being held hostage by these criminals. And they come from 25 nations across the world."
Secretary-General Ban Ki-moon said in his quarterly report to the UN Security Council on Wednesday that pirates were estimated to have received up to $30 million in ransoms this year.
In October, Russia sent the Neustrashimy (Fearless) missile frigate from the Northern Fleet to Somalia's coast to protect Russian vessels in the country's waters. The Russian warship has prevented the seizure of at least two foreign vessels in the area.
NATO and the EU have recently announced plans to increase their naval presence in the Gulf of Aden and will launch on December 8 a joint naval operation, dubbed Atalanta, against piracy near the Somali coast. The operation could involve up to 10 warships.
