The search continues in the East China Sea for 31 missing crew members from a burning Iranian oil tanker. The ship collided with a Hong Kong-registered freighter on Saturday. The Shanghai Maritime Safety Administration says just one body from the oil tanker has been retrieved. Eleven rescue ships and 6 merchant ships in the area have been involved in looking for the others. The search area has been expanded to a thousand nautical square miles. Rescue work has been hampered by an explosion on Wednesday and toxic smoke from the fire.
