How to stop a smoke bomb: This is how to take down a smoke grenade in 10 seconds

AUSTIN, Texas — A firefight has been declared in northwest Austin, Texas after a police officer shot and killed a man who was suspected of being a suspected terrorist.

The shooting was captured on video by a bystander.

Austin Police Chief Art Acevedo told reporters that the man who shot the officer was identified as 23-year-old Mohamed Youssef Abdulazeez.

Acevedos office did not identify the man, but Acevedes department did say that the suspect, Abdulazeeq Abdulazees, was killed by a single round to the chest, the Austin American-Statesman reported.

The video posted online shows the officer, who was in uniform, firing at the suspect who was holding a large smoke bomb.

Aceves office said that the smoke bomb was about 30 feet away and that the officer fired twice.

It’s unclear how many rounds were fired.

The shooting has drawn comparisons to last year’s deadly attack on a mosque in Quebec City that left four people dead and nine wounded.

Abdulazeez, a U.S.-born Muslim from Egypt, had been arrested last month on a federal terrorism charge, the Associated Press reported.

Aceveres office said the U.A.S. Department of Homeland Security had stepped in to help police with the investigation.

“At this time we believe that the individual who shot and seriously injured the officer in the line of duty is the suspect,” Aceveda said.

Witnesses in the video have described Abdulazeq as a small man, wearing a dark hoodie and dark pants.

He appeared to be in his early 20s and was seen running away from the scene.

Acevalde said the shooting was an isolated incident and no one was injured.

An Associated Press reporter in the city said the scene looked like a “bazaar of violence.”

“It was an area where people were getting ready to buy something,” said the AP reporter, who asked not to be identified.

“We have no information at this point that he was the one who shot.”

The AP also asked the U,S.

Attorney’s Office for the Western District of Texas for more information on Abdulazez.

Acevez office said they could not comment on ongoing investigations.
