8 killed in Texas school shooting

At least eight people were killed when a student opened fire on his classmates at a Texas high school today, authorities said.

"There are multiple fatalities," the sheriff of Harris County, Ed Gonzalez, told a news briefing. "There could be anywhere between eight to 10, the majority being students."

Harris said the gunman was a student at Santa Fe High School in the city of the same name, located about 30 miles (50 kilometers) southeast of Houston.
