USA: A police officer has been fired after being filmed singing a song titled ‘Let The Killing Begin’ with a death metal band — while on duty and in uniform.

WITNESSES have said the attack by armed men who stormed a party in a violent Mexican border city, killing 13 high school and college students, was prompted by false information.

Mexican Antonio Margarito made a successful fourth defence of his WBO welterweight belt after he stopped Argentinian fighter and number one contender Sebastian Lujan at the Boardwalk Hall in Atlantic City.
