Two young men, armed with guns and explosives in what appeared to be backpacks, engaged in a violent standoff with dozens of police on a street in Watertown, Mass., Thursday night, a resident said.
Andrew Kitzenburg, 29, said he looked out of this third floor window to see two young men of slight build in jackets shooting at dozens of police officers from behind a black Mercedes SUV. The officers and the men were 70 yards apart, he said, and engaged in “constant gunfire.”
A police SUV “drove towards the shooters,” he said, and was shot at until it was severely damaged. It rolled out of control, Mr. Kitzenberg said, and crashed into two cars in his driveway.
