At least four people have been killed in a small town in Texas after a line of severe storms produced multiple tornadoes in the Rolling Plains region in the north of the US state, local authorities said.

At least 10 people also were injured in Matador, a town of some 570 residents about 112km (70 miles) northeast of Lubbock, the Lubbock Fire Department said on Thursday.
