MEXICO CITY (AP) - A caravan of about 1,700 Central American migrants has arrived at the Mexican border city of Piedras Negras, just west of Eagle Pass, Texas.

Coahuila state Gov. Miguel Angel Riquelme said the migrants arrived late Sunday aboard 49 buses from the cities of Saltillo and Arteaga.

An improvised shelter was set up for the migrants at an unused maquiladora factory, and local officials said the migrants had been given sleeping mats, blankets, food and wireless access.

Previous caravans of mainly Honduran migrants had headed for the border city of Tijuana last year in their bid to reach the United States.

But Tijuana officials said their city was overwhelmed and unprepared to receive more migrants.

A second, larger caravan of several thousand migrants is expected to set out across Mexico soon.
