Two missing after barge sinks tourist boat

Rescue crews were searching today for two passengers missing after an amphibious sightseeing boat in the Delaware River off Philadelphia was struck by a barge, hurling 37 people overboard.

The six-wheeled "duck boat" which had driven into the water just after 2.30 pm yesterday local time (7.30pm Irish time), suffered a mechanical problem and a small fire, officials said. It was struck about 10 minutes later by a barge used to transport sludge, before sinking.
