Miners striking against Warrior Met Coal say they are the targets of violence.
Video shows two trucks driving toward picketers and hitting one while barely missing another. Both the Alabama Law Enforcement and Tuscaloosa County Sheriff's Office said they are not aware of any reports about the incidents in the video.
The coal company said it does not condone any acts of violence. There are more than 1,100 workers on strike who have been asking for better pay and benefits since April 1.
