Mexican Gunmen Kill Four In Ambulance Attack

Gunmen have attacked an ambulance in Mexico, killing the driver, two patients and a female passenger in the vehicle.
Two of the victims were being taken to a hospital for kidney treatment in Ciudad Juarez, officials said.
A woman accompanying the patients was also killed.
The Chihuahua state Attorney General's Office said the ambulance driver was shot in the head and appeared to be the target of the attack.
A truck carrying the gunmen first rammed the ambulance, forcing it to stop, said a spokesman for the Mexican social security institute.
The attackers then got out of the truck and opened fire on the ambulance.
Ciudad Juarez, across the border from El Paso, Texas, is at the centre of a war between the Juarez and Sinaloa drug cartels.
In 2010 there were 3,100 murders. Killings have gradually decreased but violence remains high.
Authorities reported six other murders on Wednesday in addition to the ambulance attack.
