(BBC) – Hundreds of migrants have waded into a river on the southern Mexico border as they try to reach the United States.
The migrants, mainly from Honduras, took to the water after being refused permission to cross a bridge over the Suchiate river.
Mexico has cut off migration routes to the US under pressure from President Donald Trump.
Mexican National Guard troops with riot shields tried to stop the migrants from climbing the river bank.
But hundreds appear to have breached police lines and entered Mexico.
Some reports say police fired tear gas. Some of those trying to reach Mexico threw stones at the police.
The migrants were camped out in the Guatemalan town of Tecun Uman, across the border from Mexico’s Ciudad Hidalgo.
Eight representatives of the migrants were allowed into Mexico for talks with the authorities and to pass a letter on to President Andres Manuel Lopez Obrador.
They are urging him to let them pass and promise to respect the law.
