At least three people have been killed since the caravans began their long journey toward the southern border with migrants from Central America who dream of the 'American Dream'.

A Mexican immigrant who was involved in a caravan was found dead in a road linking Tapasula and right-wing Stella, a local media reported.

Unidentified immigrants are believed to have died from respiratory illness and dehydration.

The other day, another 25-year-old immigrant drowned on the road while moving in a truck.

In the past 20 days, immigrants from Honduras in Guatemala have lost their lives on the road while driving.

Caravans are immigrants to the United States from Honduras, including Guatemala and El Salvador, where they are the most murderous in the world, and who leave their homelands to escape violence, drug crime and poverty.
