El Chapo's sons accused of deadly attack on Mexican army convoy

SINALOA, Mexico, Oct. 1 (UPI) -- The sons of Mexican drug lord Joaquin "El Chapo" Guzman are suspected of an attack on a Mexican army convoy that killed six soldiers and wounded nine others early Friday morning, officials said.

The convoy included an ambulance that was transporting a prisoner to a hospital in Culiacan, in the western state of Sinaloa, said state public safety coordinator Moises Melo, when it was attacked by up to 60 men armed with grenades and assault rifles.

"Up (to) this point we are not certain about this group, but it is very probable that it was the sons of Chapo," said commander of the 3rd Military Region, Gen. Alfonso Duarte.

The gunmen set two army vehicles on fire and stole the ambulance transporting the prisoner, identified as Julio Oscar Ortiz Vega.

Four soldiers were pronounced dead at the scene, and two more later succumbed to their injuries. Eight other soldiers and a Red Cross paramedic were also injured.
