This story, the video, Finding Freedom Amid Ruins: The Free Runners of Gaza fills me with such sadness... too much to contain alone in my room in front of my screen. It all seems so sci-fi-dystopia but it's real. Haunting.

They proceed to show videos of Israeli rockets filmed dangerously close to the points of impact. “We want the world to know what we do, how tough the situation is,” one of the North’s players says.

“We used to climb that mosque,” one says pointing to a tower. “But there’s a dud in there now.” The same can be said of the rest of the city, with many unexploded bombs and shells still trapped under the rubble – the very obstacles the teams depend on to perform their death-defying jumps and somersaults.

Both teams are preparing for the upcoming competition. All of them are incredibly fit, despite the scrawny statures. They can grapple and climb like agile cats, making every trick look easy in the blistering heat.

Watching this, all at once I feel overwhelmed with the sense the incredible resilience of the human spirit - these kids are amazing - but also the intensity, and power, of those who would crush it. And for what? Again, same answer as always: Greed, fueled by Hate.

The sport of free-running – or parkour – has found a home with youths in battered Gaza. The ruins and debris left in the wake of the 2014 bombing campaign by Israel have become a source of both mortal danger and endless inspiration.

RT Documentary travelled to the area, where debris and dilapidated structures line the desolate landscape, setting the stage for two sworn rivals – Gaza Parkour, from the South, and 3Run Gaza, from the North.

Most residents try hard to maintain a sense of normality amid the unchanging scenes of damage that will take decades to repair. But for the two teams this apocalyptic landscape provides a rich training ground for their extreme sport.

“Parkour is freedom. And there's no freedom in Gaza. People get their freedom through parkour,” says one of the free-runners.

What are we doing? Humans I mean. How is this allowed...
