DALLAS (AP) — Federal prosecutors in Texas have charged six more individuals with new terrorism-related offenses in connection with the July 4 shooting outside an immigration detention center near Dallas. The announcement made on Friday indicates that six others are also expected to enter guilty pleas in relation to the case.

The recent indictment broadens the previous charges under President Trump’s recent characterization of antifa as a domestic terrorist organization, attributing the movement with political violence.

This case originated from an incident at the Prairieland Detention Center in Alvarado, where a police officer was injured. Allegations against the group include rioting, attempted murder, and possession of weapons and explosives. Prosecutors assert that the group not only threw fireworks at the facility but also vandalized vehicles and fired upon responding police and correctional officers, resulting in injuries to an Alvarado officer, who has since been released from medical care.

The shooting incident coincided with a period during which the Trump administration intensified deportations.

Patrick McClain, the attorney representing defendant Zachary Evetts, has publicly stated that he views the government's claims as unsupported by evidence. At the upcoming arraignment scheduled for December 3, Evetts plans to plead not guilty to the new charges introduced.

Short for 'anti-fascists,' antifa is described as an umbrella term for a collection of left-leaning groups engaging in confrontational actions against neo-Nazis and white supremacists.
