Migrant caravan en route to Mexico City for faster US legal process.

Thousands of migrants, mostly Venezuelans, have formed a new caravan in southern Mexico to head for the capital, Mexico City, to speed up their applications for U.S. asylum. The new caravan has about 3,000 migrants, some from China and other Asian countries. The migrants are protesting against the detention centers and demanding their closure. They hope to reach Mexico City in about 10 days.
