Fiery and deadly

FORT LAUDERDALE — Two big rigs and two passenger vehicles collided and spilled diesel fuel across a Florida highway Thursday, sparking a massive fire that killed seven people, authorities said.

The wreck happened on Interstate 75 about a mile south of Alachua, near Gainesville. The flames were fed by about 50 gallons of diesel, authorities said.

Several others were taken to the hospital, some with critical injuries, Gainesville Sun reported.
