Explosion rocks Sunoco chemical refinery

Massive explosions rocked the Sunoco refinery in the Marcus Hook area tonight, sending flames shooting into the night and sounding alarms in three states.

The actual explosions were in Delaware but close to the Pennsylvania border. Some officials were reporting that the chemicals in the explosion could waft into South Jersey. The explosions were first heard shortly after 10 p.m.

The flames could be seen as far as 10 miles away at the Philadelphia airport.

Safety officials were considering widespread evacuations and police were blocking off roads around the refineries, one of the largest on the East Coast, according TV reports.

Sunoco officials did not have official information on the cause. A union official said he did not know if anyone was hurt but that the refinery was staffed.
