A video circulating on the Internet that appears to show allegiance to the Islamic State ends with footage of San Francisco that features shots of the Golden Gate Bridge and the 555 California street tower — an apparent threat that officials said has not been confirmed as legitimate.

The video praised the Orlando shooter using a combination of news reels, screen shots from newspaper articles, and speeches from various men in a mix of a languages.

KPIX 5 reports that ISIS says “Arise, o Muslims and kill the unbelievers in their own homes” when the shot of the Golden Gate Bridge appears.

That was followed with a shot of Las Vegas, and a shot of Pine Street with the Financial District in the background that appeared to have been taken from a cable car.

The FBI was investigating the film’s origins.

“We are aware of the video,” said FBI spokesman Prentice Danner. “We can’t confirm it’s validity. We’re not aware of any credible threat.”

The video has an ISIS flag in the upper right-hand corner, and lasts more than nine minutes.

One of the men in the video says he wants to “pay tribute” to Omar Mateen, the Orlando shooter, referring to him and another man as “my brothers,”

“You have pleased our hearts, you have pleased the hearts of Muslims,” the man said in French, adding they should not worry about “hate from the hypocrites of the Muslim community.”
