Two dozen gunmen burst into a casino, doused it with gasoline and started a fire that trapped gamblers inside, killing 53 people and injuring a dozen more in northern Mexico.
A drug cartel was apparently responsible for yesterday's tragedy at the Casino Royale in Monterrey.
It was one one of the deadliest attacks on an entertainment centre in Mexico since President Felipe Calderon launched an offensive against drug cartels in late 2006.
Calderon tweeted that the attack was "an abhorrent act of terror and barbarism".
