At least five people have been shot and killed, after a gunman opened fire at a shopping centre, in the US state of Washington.
Police in northwest Washington state on Saturday conducted a manhunt for a gunman who opened fire in a mall, killing four women and critically wounding a man, media said.
A man walked into the Cascade Mall in Burlington, Washington, about 65 miles (105 km) north of Seattle and began shooting at about 7 p.m. local time on Friday, Washington State Patrol spokesman Mark Francis said on Twitter.
He also said police were searching the area for the shooter, who was described as a “Hispanic male wearing gray” and last seen walking toward a nearby highway away from the mall.
Local authorities searched throughout the night for the gunman, believed to be armed with a rifle and warned residents to remain inside.
The shooting comes less than a week after a man stabbed nine people at a mall in central Minnesota before being shot dead. The FBI is investigating that attack as a potential act of terrorism.
NBC News reported that Washington State Patrol had said that there was no indication of terrorism in the shooting in Burlington.
