Watch: 'It's not the kids' fault!' - 13 Year Old British passport holder tells realities of war in Gaza

“The kids are playing in the park, with the bombs going off… It’s unsafe, it’s not fair. I feel bad for the kids. It’s not the kids’ fault that this war happened. It’s no one’s fault… it shouldn’t be happening,” Abu Assi told Reuters, in his native English, from a playground with his siblings and parents nearby.

Abu Assi said the move has been “stressful for everyone,” and hoped that the borders of the southern Gazan city of Rafa will open up, allowing him and his family to evacuate to Egypt safely.

“Homes have been destroyed, there’s people sleeping on the streets, you can see rubble nearly everywhere you go. It’s really, it’s horrible. There’s fires, smoke, anywhere you look. There’s sand everywhere. It’s like a war zone. It is a war zone,” said a clearly tired 13-year-old Abu Assi, whose parents gave Reuters permission to speak to him as he is minor.

Israel has urged exhausted Gazans to evacuate south, which hundreds of thousands have already done in the besieged enclave that is home to more than 2 million people. Hamas, which runs Gaza, has told people to ignore Israel's message.

Inside Gaza's narrow and crowded streets, conditions are deteriorating as deaths from Israeli air strikes rise. Bodies are being stored in ice cream freezer trucks because moving them to hospitals is deemed too risky and cemeteries are full.

“If Rafah doesn’t open we could be in serious trouble. I don’t know what to do. I’ve been this war, I don’t know, five, six days now. I’ve lost track of the weeks. It really has been so stressful,” he said.
