Mexico's president said Wednesday that he would consider a request by convicted drug lord Joaquin "El Chapo" Guzman to return from the United States to complete his sentence on humanitarian grounds.
The Sinaloa cartel founder has appealed to President Andres Manuel Lopez Obrador for help due to alleged "psychological torment" that Guzman says he is suffering in a US prison.
"We're going to review it (the plea)," Lopez Obrador told reporters.
It was unclear if Mexico had the power to grant the request, "but the door must always be left open when it comes to human rights," he added.
El Chapo is serving a life sentence in a maximum security prison in Colorado after being convicted in 2019 of charges including drug trafficking, money laundering and weapons-related offenses.
According to one of his lawyers, Jose Refugio Rodriguez, Guzman is unhappy with the harsh prison conditions including isolation and a lack of sunlight.
He hopes to return to face outstanding charges and complete his sentence in Mexico under a prison agreement between the two countries, Rodriguez told AFP.
On Tuesday, Mexican Foreign Minister Marcelo Ebrard had downplayed the chance of any government intercession in favor of Guzman, who twice escaped from jail in his home country.
"Frankly I don't see any possibilities for him, but I'm going to review it with the prosecutor's office," Ebrard told reporters.
One of El Chapo's sons, Ovidio Guzman, was arrested by Mexican security forces this month in an operation that left 29 people dead and sparked a dramatic shootout at an airport in the city of Culiacan.
