Three US citizens are killed in Mexico

WASHINGTON - Three Americans were fatally shot over the weekend in Ciudad Juarez, Mexico's notorious murder capital and a focal point of its brutal drug violence, United States officials said on Monday.

US State Department spokesman Philip Crowley said it was not clear if the three Americans were killed in deliberate attacks, or if they were simply in the wrong place at the wrong time.

"We offer our condolences to the families of the victims," he said.
