Hundreds of migrants travelling across Central America in a mass caravan to the US have tried to breach Mexico’s southern border and enter the country.
Some migrants broke through Guatemalan border fences but then clashed with Mexican riot police in no man’s land.
On Friday, US President Donald Trump thanked Mexico for holding back the migrants from crossing into the US.
The migrants, mostly from Honduras, say they are fleeing violence and poverty, and include women and children.
President Trump, who has threatened to close down the US border, said the military would be called upon if needed.
