(CNN) -- The Federal Emergency Management Agency has denied additional aid tied to deadly explosions at a Texas fertilizer plant, a decision ripped Wednesday by local and state officials who accused President Barack Obama of having "gone against his word." FEMA's administrator informed Gov. Rick Perry in a letter Monday that it was denying a request to declare West, Texas -- the small town where an April 17 fire led to simultaneous blasts at a fertilizer distribution facility, killing 15 and decimating homes, businesses and more within 37 blocks -- a "major disaster" area. The letter noted Obama had previously issued an emergency declaration and other measures that paved the way for some direct federal assistance.
