A tornado has injured dozens and killed at least five people in Canton, a small city in the east of Texas Saturday.
Capt. Brian Horton of the Canton Fire Department told reporters late Saturday that numbers were "still coming in," but there were "maybe five casualties." The number could rise as search teams expand their operation in the morning, he said.
"We still may have some people that aren't accounted for," he said.
At least 54 people went to hospitals and one person is in critical condition, ETMC Regional Healthcare Systems spokeswoman Rebecca Berkley told The Associated Press.
Texas Gov. Greg Abbott tweeted that the Texas Task Force 2 search and rescue team had been dispatched to help the city and surrounding Van Zandt County.
The National Weather Service reported multiple tornadoes in northeast Texas Saturday.
People on Twitter captured footage of the tornado.
Pictures on social media show crushed cars, destroyed buildings and trees stripped of branches and leaves.
Horton, of the Canton Fire Department, told reporters that a triage has been set up at a high school, the AP reports. He asked for people to stay out of the affected area, "so that our teams can do what they need to do to take care of these people who are in need."
