Mexico moves to block new US-bound migrant caravan

Mexico moved Tuesday to block a new caravan of around 100 Central American migrants seeking to reach the United States after they crossed the Suchiate River from Guatemala into Chiapas state.

Local news footage showed Mexico's National Guard, immigration authorities and police positioned across a road to stop the group near the southern border. As officers surrounded them, the migrants began running.

Reports from Tapachula, the city closest to the border, said around 40 people were detained. Mexican immigration authorities did not immediately confirm the arrests.

The attempted crossing came three days after a larger caravan of about 1,000 US-bound migrants entered Mexico on Sunday evening without encountering resistance. That group stopped in Tapachula before resuming its journey toward the United States, although the border remains virtually closed.
