A convoy of 1,500 to 2,000 migrants is heading towards the US border from southern Mexico. People left the city of Tapachula in the state of Chiapas.
Most of the participants are from Honduras, El Salvador and Guatemala. They are marching under the slogan "Immigration is not a crime".
Some hope that after the Democrats win the US Congress, immigration policy will soften. At the same time, the authorities in the US and Mexico previously announced strict border control.
