Ismailia, EGYPT: An undated file photo shows the Egyptian dredger Khattab that sank in the Suez Canal before dawn 13 September 2006, leaving two crewmembers dead and two others missing, and causing a temporary closure of the major international waterway. After a one-hour closure, traffic was diverted to the canal's western channel allowing all scheduled ships to go through, authorities said.
