About 200 participants in a protest convoy of Central American migrants have arrived in Mexico's capital and filed abuse complaints with the government's National Human Rights Commission.

The agency says in a statement that an ombudsman met on Saturday with representatives of the protest. It says they turned in 139 complaints alleging violations against migrants by Mexican federal police and immigration officers.

The protesters were accompanied by the Rev. Alejandro Solalinde, who runs a shelter for migrants in southern Mexico. He charged that federal agents had "committed various violations of human rights" against migrants

He called for an investigation of events at a road checkpoint in the southern state of Oaxaca, where he has said officers tried to prevent the protest convoy from heading to Mexico City.
