Five people were killed and three others badly wounded in an attack on a street vendor's stand here in this Mexican border metropolis, authorities said Friday.

At least four gunmen were involved in the shooting on the south side of Ciudad Juarez, Chihuahua state Attorney General's office spokesman Arturo Sandoval told Efe.

"The (victims') identities remain unknown, but the dead are between 15 and 20 years old and the wounded are two minors and a lady of 38," he said.

Three people were pronounced dead at the scene, while the other two died en route to the hospital.

Juarez, located just across the border from El Paso, Texas, is Mexico's murder capital, with more than 9,000 reported homicides since the start of 2008.

Most of the killings are attributed to a vicious territorial battle between the Juarez and Sinaloa drug cartels.

Drug-war violence has claimed nearly 50,000 lives across Mexico since December 2006, when newly inaugurated President Felipe Calderon militarized the struggle against the cartels.
