ESTELI, NICARAGUA (AFP) - A road accident in northern Nicaragua has left 16 people dead, including 13 Venezuelans believed to be migrants, police said on Thursday (July 28).

The accident - which left another 47 people injured - occurred late on Wednesday at a precarious crossroads on the Pan-American Highway in the department of Esteli.

"Sixteen people died, amongst them five women and 11 men - 13 Venezuelan nationals, a Nicaraguan and two yet to be identified," national police said in a statement, describing the accident as a "total disaster."

Officers believe the incident occurred when a speeding bus hit two cars.

"As a result of the collision and excess speed, the bus driver lost control and (the bus) fell into a ravine," said the police statement.

On Thursday, the bus remained upside down in the ravine, which is around 80m deep, an AFP reporter at the scene said.

The bus driver was arrested.

There were "many injured, people's cries, some calling out for their companions, children - it's painful," said local resident Mario Jose Rugama.

"Those poor people, how they screamed - they came out with fractures, covered in oil because the bus turned over... so the people were bathed in hot oil."

Many migrants trying to reach the United States pass through Nicaragua and other countries in Central America.
