Mexican President Andres Manuel Lopez Obrador said Friday there were indications that a US-bound migrant caravan traveling through Guatemala had been organized to draw his country into the US election campaign. "It seems very strange to us. It's very strange that this caravan leaves on the eve of the election in the United States," Lopez Obrador told reporters. "It has to do with the election in the United States. I don't have all the elements but I think there are indications that it was put together for this purpose," he added. Thousands of migrants surged across the border from Honduras into Guatemala on Thursday, just weeks before a tense US presidential election where immigration is a key issue. In recent years, thousands of Central American migrants traveling in large groups have crossed into Mexico, with the aim of reaching the US border. US President Donald Trump, who is seeking a second term in the November 3 election, has threatened Mexico with steep US tariffs if it does not do more to stop a surge of undocumented migrants. jla/dr/dw
