Five people dead in Cali and another three in Medellin is the death toll in several confrontations staged Sunday by gangs in different parts of these two Colombian cities, authorities said.

In Cali, in the southwest, five people were shot to death and three others wounded in several incidents.

According to a report by the city's Metropolitan Police, the shootings occurred late Saturday night or early Sunday morning in the Mojica, Bonilla Aragon and Potrero Grande neighborhoods, all located in the violence-plagued Aguablanca district where youth gangs have a strong presence.

Among the dead was one teenager, a 36-year-old woman and a businessman killed outside his home by assassins riding a motorcycle.

In various operations in Cali, police captured one of the alleged killers.

Meanwhile, in the northwestern city of Medellin, three people, including one minor, were murdered in a presumed settling of scores in the municipality of Bello, in the Medellin metropolitan area, authorities said.

The killings occurred on Saturday night when three young men were approached on foot by masked gunmen and shot.

Authorities identified two of the victims as Elmer Alonso Pulgarin, 24, and Jeimar Alexander Bustamante Carvajal, 20. The minor, whose identity was not revealed by police, was 14. EFE
