One person died and at least five others were injured Wednesday when a petrol station exploded in the western Argentine province of Mendoza, local authorities said. The accident happened in the town of Rodeo de la Cruz, 15 kilometres from provincial capital Mendoza, and residents were evacuated from the area. "We have to determine whether there were faults in the security valve system of the tank," dpa quoted Mendoza Civil Defence director Rafael Garay as saying.
