Mexico Accidentally Invades Texas

What may have been the largest incursion by foreign troops onto US soil since the Japanese invasion of Alaska's Aleutian Islands occurred in Texas this week. Four Humvees carrying a total of 33 Mexican soldiers accidentally strayed into US territory, crossing the boundary line on a bridge across the Rio Grande and continuing as far as the inspection area.

"They were processed according to protocols, and they were released and returned to Mexico without incident or charges," a Customs and Border Protection rep tells Reuters, noting that similar incidents have happened before. The Mexican military says its troops inadvertently crossed over the bridge while they were carrying out reconnaissance on the border. (More Customs and Border Protection stories.)
