Three people have died after a gunman opened fire in broad daylight outside a Walmart store in Oklahoma.
Two men and a woman were shot dead at about 10am local time on Monday (4pm UK time), police said.
It comes hours after four people died and six were injured in a shooting at a party in Fresno, California.
Police Chief Danny Ford said two of the Oklahoma victims were shot inside a car and the third was in the parking lot outside the store in Duncan, near the border with Texas.
Police are looking for witnesses to the shooting, Mr Ford said.
A dispatcher told The Associated Press that "everyone is at the scene."
Duncan is about 80 miles south of Oklahoma City.
