Hundreds of people are stuck between the border of Peru and Chile, some without food or water.

Peruvian Prime Minister Alberto Otarola said on Saturday that dialogue with other governments has “moved forward” on what he calls the “migrant crisis.”

Hundreds of people remain stranded, unable to cross the Peruvian border to return to their home country of Venezuela.

Tensions between migrants and Peruvian citizens seeking to cross over to the Chilean side led to clashes with rocks early Saturday.

One person was injured.

The consular authorities of Venezuela have appeared in this area, seeking to help their compatriots.

The migrants faced the inhospitable climate of the Atacama Desert, one of the driest on the planet, with heat during the day and bitter cold at night.

Most of them are not adapted for such adverse conditions.

According to international organizations, including the UN, hundreds of stranded migrants include families with children and extremely vulnerable people.

On Friday, Chile said it would start registering all undocumented migrants who want to leave the country, and Peru has begun letting some of them into its border offices.
