Animal rights activists have claimed responsibility for the Sunday arson fire that heavily damaged 14 tractors and several cattle trailers at Harris Farms in Fresno County, California, according to a clearinghouse for activists.

The animal liberation underground group that the FBI identifies as a domestic terrorist organization, claims to have set the fire that started just before 4 a.m. Sunday at the truck storage area at Harris Farms feedlot. In an e-mail to the Fresno Bee, Harris Farms CEO and Chairman John Harris said the company was “appalled by this senseless, but very alarming attack. I had suspected Animal Liberation Front may have been involved and now they are in fact claiming responsibility for it with multiple details.”

The clearinghouse that distributed the statement claiming credit for the arson is the North American Animal Liberation Press Office, which says it has no direct dealings with underground groups or illegal activity.
