Mexican President Felipe Calderon is deploying 1,500 troops to Monterrey following a deadly casino attack that left at least 52 dead.

The Thursday attack drew universal condemnation across Mexico and the world.

President Calderon has promised swift action and justice.

On Saturday, Mexico's Ministry of National Defense (SEDENA) confirmed that 1,500 troops will be deployed to Monterrey.

Some 600 troops aboard two planes are expected to land in Monterrey for the first phase of the operation within the next 72 hours.
