Mexican drug kingpin Joaquín "El Chapo" Guzmán has been found guilty on all 10 counts at his drug-trafficking trial at a federal court in New York.
Guzmán, 61, was convicted on numerous counts including the distribution of cocaine and heroin, illegal firearms possession and money laundering.
He has yet to be sentenced, but the verdict could mean life in jail.
Guzmán was arrested in January 2016 after escaping from a Mexican prison through a tunnel five months earlier.
He was extradited to the US in 2017.
The Mexican was accused of being behind the all-powerful Sinaloa drug cartel, which prosecutors say was the biggest supplier of drugs to the US.
