Tornadoes touched down several times in northern Texas.
A tornado has ripped through a town in the US state of Texas, resulting in six deaths, officials say.

Severe weather has been reported across the region. One resident described the tornado's impact to Reuters: "The house started shaking. We were in a closet. "You could hear it - it sounded like a train going off. It was scary," he said.
The same storm spawned another tornado that tore through part of the town of Cleburne, about 25 miles (40km) south-east of Granbury, the national Weather Service said. There have been no reports of any fatalities from Cleburne so far. However, dozens of homes have been destroyed or badly damaged, according to officials and residents.
A third tornado in neighbouring Parker County has also caused damage to buildings, particularly in the town of Millsap, officials say.
