A man identified as an American ISIS fighter praised the Orlando nightclub gunman and urged more attacks on the U.S. in a video released by the terror group on Sunday – exactly one week after Omar Mateen slaughtered 49 people inside a Florida nightclub.

During Mateen’s massacre, which also wounded 53 people, he called a 911 operator to pledge allegiance to ISIS. The terror group quickly claimed credit for the attack; however, officials have said there was no direct guidance from the jihadist organization. Rather, it is believed Mateen was only inspired by ISIS to carry out his assault on Pulse, a gay nightclub.

But in the new video, identified by the non-governmental counterterrorism organization SITE, the American fighter urges other Muslims to be inspired by Mateen’s actions.

“Omar Mateen, one of the soldiers of the [caliphate], was one of the few that was truthful to his lord,” Abu Isma'il Al-Amriki says. “While having prepared his weapons and taken steps, while having trust and reliance upon Allah, it is through his hand that Allah punished his enemies.”

Al-Amriki, which translates to “The American,” speaks in English and appears in a desert setting dressed in military-style fatigues and holding a rifle. Arabic music plays quietly as he speaks and Arabic subtitles are featured on the bottom of the screen. The video was released by ISIS’ branch in western Iraq, according to SITE.

ISIS terrorists of French, Indonesian, Russian and Uzbek backgrounds also appear in the video.

One of the Islamists reference a “surprise” operation during the Euro 2016 tournament in France, NBC reported.

The slogan “You are not held responsible except for yourself” is also featured in the video, with an image of President Obama on one side, Mateen on the other and images of the Orlando slaughter in-between.

“Do you think you’re at war with a small group of Mujahedeen in Iraq, Syria, Libya and other places? You are sadly mistaken. And do you think you can defeat us by bombarding our homes with the help of your drones and F-16s [and government groups]? Then again, you have sadly made a great mistake,” Al-Amriki says. “Oh America, indeed you are at war with all the true and sincere Muslims around the world.”
