A fire official says a large fire has broken out at the Blue Grass Stockyards complex in Kentucky.

Lexington Fire Department spokesman Joe Best says the blaze is one of the largest he has seen in his 25 years with the department.

He told The Associated Press that a call came in to the department about 2:20 p.m. Saturday. Around that time, AP reporter Adam Beam saw thick black smoke coming from the area and heard explosions.

Best says he does not yet know whether there have been any injuries to humans or animals.
