Awwal 08, 1432, Feb 11, 2011, SPA -- Greek authorities say pirates have freed two merchant navy officers kidnapped from a Greek-managed cargo ship off the coast of Nigeria last month, according to AP. The Merchant Marine Ministry says the two _ the Ukrainian captain of the Perseus and its Greek first engineer _ were released on Friday morning. They had been kidnapped in a Jan. 26 attack on the Perseus which left two Egyptian sailors wounded. The ministry says the two are at a naval base in Nigeria, and will be undergoing medical checks before returning home, possibly on Sunday. The St Vincent and Grenadines-flagged Perseus had a crew of 15 Ukrainian, Greek, Syrian, Egyptian and Filipino seamen.
