At least five people were killed and 21 others injured when a gunman opened fire at random on Saturday in the second mass shooting in Texas in a month, police said.

The shooting — the 38th mass killing by firearms in the US this year — occurred in the West Texas cities of Midland and Odessa. The gunman, who was white and in his mid-30s, was shot dead by police after a chase. However, police did not identify him by his name.
