Migrant caravan fragments as hundreds return to the road

The caravan of Central American migrants whose trek toward the United States became a hot-button issue in the US mid-term elections fragmented Friday as hundreds left Mexico City to resume their journey. Around 5,500 migrants had been camped out in a shelter set up at the weekend inside a stadium in the capital. The caravan set out on October 13 from San Pedro Sula, Honduras, and has covered more than 1,600 kilometers (1,000 miles) so far.
