Mexican drug lord 'El Chapo' found guilty

The Mexican drug lord, known as 'El Chapo' has been found guilty on 10 counts of drug trafficking. The 61-year-old, who's real name is Joaquín Guzmán, was accused of being behind the all-powerful Sinaloa drug cartel, which prosecutors say was the biggest supplier of drugs to the US. US prosecutor Richard Donoghue says El Chapo was responsible for murder, violence and trafficking over a period of decades.
