By DEREK GATOPOULOS and NICHOLAS PAPHITIS (Associated Press) KALAMATA, Greece (AP) — A fishing boat crammed to the gunwales with migrants trying to reach Europe capsized and sank Wednesday off the coast of Greece, authorities said, leaving at least 79 dead and many more missing in one of the worst disasters of its kind this year. Coast guard, navy and merchant vessels and aircraft fanned out for a vast search-and-rescue operation set to continue overnight.
