Donald Trump threatened to double tariffs unless Mexico stops migrant caravans heading towards the United States. The warning sharpens tensions after Republican midterm losses and a northbound migrant march.

US President Donald Trump has threatened to immediately double tariffs on Mexico unless the country stops what he described as large migrant caravans moving towards the US border, escalating his post-midterm confrontation with Mexico.In a sharply worded post on Truth Social on Thursday, Trump claimed that a new "invasion" was underway after Republicans suffered heavy losses in the US midterm elections. He argued that large groups of migrants were forming and travelling through Mexico towards the United States.Trump also stressed that he himself was not on the ballot in the November 3 elections, repeating an argument he has made several times since the Republican defeat.The threat comes just a day after more than 1,000 migrants began walking north through southern Mexico.

News agency Reuters reported that the group, estimated at about 1,500 people, left Tapachula near the Guatemalan border and was heading towards Mexico City. - Ends
