Greek officials say the bodies of a woman and an 11-year-old boy have been found a day after a fishing boat crammed with immigrants capsized in the dark, leaving 12 people feared drowned in the Aegean Sea.

A coastguard statement says the two bodies were located Tuesday by authorities on the nearby Turkish coast. The crippled vessel, whose engine failed as it was trying to reach Greece illegally, was being towed by a Greek patrol boat when it overturned.

Wednesday's statement says photos of the bodies were identified by some of the 16 survivors. Their nationalities were not announced.

The United Nations refugee agency has expressed dismay at the accident, urging Greece to investigate the circumstances. Greek authorities say the boat capsized during a panic after two passengers dived overboard.
