New footage of the Sydney attacker released; the video is chilling VIDEO/PHOTO

As seen in the footage, the suspect in the terrorist attack gestured with his hand and warned passersby to move away, while simultaneously continuing to fire at the crowd during the Hanukkah celebration.

The video was released by Australian media and can be viewed HERE.

So far, reports indicate that at least 15 people were killed in the attack, while dozens more were injured.

Police have identified the attackers as Naveed Akram (24) and his father Sajid Akram (50).

They opened fire on attendees at the “Hanukkah by the Sea” event, held to mark the first night of Hanukkah, at Bondi Beach in Sydney around 6:40 PM on Sunday.

Released footage from the pedestrian bridge

The videos show the attackers standing on a pedestrian bridge, raising firearms, and aiming in one direction while people fled in the opposite direction.

At one point, the older Akram descends from the bridge to approach the crowd, while the 24-year-old remains above, continuing to shoot.

Sajid Akram was later disarmed thanks to 43-year-old Ahmed al Ahmed, who was filmed sneaking up behind the attacker, tackling him to the ground, and taking his weapon.
