The incident took place at the entrance of the U.S. Border Patrol sector annex in McAllen, a city in southern Texas that borders Mexico, according to the DHS spokesperson. Mosqueda fired dozens of rounds toward the building and agents inside, Rodriguez said.

Road closures were continuing while officers searched an area where a man who was believed to be wielding a chainsaw and wearing a gas mask was shot by police in Kent.

FOX 26's Sherman Desselle provided early information at the scene.
