'El Chapo' files legal challenge against extradition to U.S.

Lawyers for Mexican drug boss Joaquín "El Chapo" Guzmán have filed a legal challenge against a decision by the foreign ministry to approve his extradition to the United States. 

A judge granted him "provisional suspension", meaning that the foreign ministry has 48 hours to present a report justifying its decision, Mexican newspaper El Universal reported.

Mexico's Foreign Ministry approved Guzmán's extradition to the United States earlier in May, and said it had received guarantees that the death penalty would not be sought against him.
