National Guardsmen overrun by gunmen on Mexican border

I wondered when this would happen back in March, when the National Guard was first ordered to the border. Seems my question has been answered.

Breaking from local Arizona News 12

A patrol of four National Guardsmen was overrun by armed men at the border somewhere between Nogales (AZ or Mexico; they're right across from each other) and Lukeville, AZ, a 120 mile stretch of desert in the western part of the state's border with Mexico on the night of January 3rd. No one was hurt and the gunmen retreated back to Mexico when Border Patrol reinforcements were called. It's unclear whether shots were fired. The Guard is currently deployed along the border on orders from the Arizona governor, and is in an observation and support role, supplementing the Border Patrol rather than directly acting against border incursions.

I will post updates later today as information warrants. I haven't slept all night and am too tired to go hunting for additional sources at the moment.

Update: MSNBC now has a more detailed article up.
