Twenty-one people are dead in Mexico following a massive gun battle between rival drug and migrant-trafficking gangs near the US border.

Police killed 15 gunmen in a fierce battle just south of the Arizona border after tracking assailants believed to have abducted and killed five Mexican policemen into the nearby hills with a helicopter.

Tom Green believes it’s his outspoken nature more than his polygamist lifestyle that has led to his prosecution in Utah’s first high-profile bigamy case in 50 years.
