Alvarado, Texas — Ten people have been arrested on attempted murder charges in connection with a shooting outside of a Texas immigration detention center that wounded a police officer, where people in black military-style clothing fired at authorities in a “planned ambush,” a U.S. attorney said.

Federal prosecutors in Texas have charged 10 people with attempted murder following what they called an "ambush" of law enforcement late Friday outside an Immigration and Customs Enforcement detention facility.
