MIAMI —  A massive cargo ship that caught fire over the weekend is smoldering in Miami.

The 200-foot freighter caught fire on the Miami River as it was carrying cars, mattresses and bicycles to Haiti.

A Miami-Dade Fire Rescue spokesman said Tuesday that about 60 firefighters are still working to control the embers. Extinguishing the remnants has been difficult because the ship was packed with goods.

The spokesman says the ship had started to tilt but was being secured with tugboats and lines. Crews say they expect it to reignite as they keep working.

More than 100 firefighters spent three hours Saturday night putting out the fire and it briefly rekindled Monday. Investigators don't know the cause.
