U.S. Deputy Secretary of State John Sullivan wants stronger efforts to stem the flow of heroin and fentanyl from Mexico, as the U.S. government is criticizing lower opium poppy eradication in Mexico. Sullivan said on Monday, Oct. 23 2017, that the U.S. wants “more rigorous, collaborative efforts” against heroin and synthetic opioids. (AP Photo/Dario Lopez-Mills)
