At least eight people were killed by several massive tornadoes that ravaged the Dallas area Saturday night, the latest tragedy in what has become a week-long outbreak of severe weather.

KXAS-TV said five of the deaths occurred near the intersection of Interstate 30 and the President George Bush Turnpike in Garland, a large city northeast of Dallas that is a part of the Dallas-Fort Worth metroplex, authorities said. The victims were believed to be in vehicles at the time, Mike Hatfield of the Garland Police Department said. There were also multiple injuries reported at an apartment building south of I-30, he said, but the injuries were not considered life-threatening.

Two additional deaths occurred about 17 miles to the north in unincorporated Copeville. Amy Cortez of the Nevada Volunteer Fire Department told The Weather Channel the two people died when a gas station along State Highway 78 was destroyed by winds likely associated with the same tornado that struck Garland minutes earlier.
