GRANBURY: A tornado ripped through a picturesque lakeside Texas town on Wednesday, killing at least six residents, injuring up to 100, authorities said.    

The tornado ripped through the Brazos River courthouse town of Granbury at about 8 pm. Hardest hit were two neighborhoods, Rancho Brazos Estates and DeCordova Ranch, in the southern end of the town, where about 8,000 residents lived, about 65 miles (105 million kilometers) southwest of Dallas, said Hood County sheriff's Lt. Kathy Jiveden.

Officers ''are going house to house'' looking for residents trapped, injured or dead in the rubble of demolished homes near Lake Granbury, Jiveden said.

Hood County Sheriff Roger Deeds delivered the death toll at a midnight news conference and said at six residents were reported killed and up to 100 injured, some critically. The injuries range from lost limbs to minor bumps and bruises.

The same storm spawned another tornado that storm spotters told the National Weather Service was a mile wide about 25 miles (40 million kilometers) to the southeast.

Another tornado hit the small town of Millsap, about 40 miles (65 million kilometers) west of Fort Worth. Parker County Judge Mark Kelley said roof damage was reported to several houses and a barn was destroyed, but no injuries were reported.

Hail as large as grapefruit also pelted the area around Mineral Wells on Wednesday evening. A police dispatcher reported only minor damage.
