The rockets began around 6:30 a.m., Tal Gibly told CNN. Thirty minutes later, she and hundreds of others attending a music festival were running as Gaza militants fired at them.

The outdoor event in a rural farmland area near the Gaza-Israel border was supposed to be an all-night dance party, celebrating the Jewish holiday of Sukkot. But as dawn broke, Gibly said they began hearing sirens and rockets.

“We didn’t even have any place to hide because we were at [an] open space,” she told CNN. “Everyone got so panicked and started to take their stuff.”

Explosions can be heard in video taken by Gibly of her and friends walking through the quickly emptying concert grounds, roughly two miles from the border.

“Ima’le,” someone is heard saying, a common Israeli expression of fear or feeling startled.

Gibly and the others didn’t know it, but less than two miles away, Gaza militants had also begun attacking Israeli tanks and soldiers.
