And it begins . . .

Gunfire was exchanged across the Mexican border over the weekend, when Border Patrol agents were shot at while seizing a drug shipment, the Customs and Border Protection agency said on Tuesday.

The incident occurred on September 11 around 7:40 a.m. near Mission, Texas, a CBP spokesperson told the Daily News.

"Several Border Patrol Agents returned fire after being fired upon multiple times from the Mexican side," the agency said in a statement.

It is unclear who fired at the agents, or how many were involved. Authorities were in the process of seizing a shipment of marijuana when the gunfire broke out.

The most serious terrorist threat to America is not based in Afghanistan or Iraq or Pakistan. It's on the other side of our unprotected border with Mexico.
