Mexico is preparing to significantly reinforce efforts to detain U.S.-bound migrants who illegally cross its border with Guatemala, in response to a jump in people trying to enter the United States. Reuters quotes people familiar with the plan as saying that Mexico would deploy security forces to cut the flow of migrants, the bulk of whom come from Central America’s so-called Northern Triangle of Guatemala, El Salvador and Honduras, whose economies were battered by the coronavirus pandemic and hurricanes last year. The people did not give details of the new migration plan, but similar operations in the past have focused on catching migrants on a narrow isthmus in the south of the country, rather then trying to stop all crossings on the Guatemalan border where remote and difficult terrain complicates efforts.
