These kids are making their own no-fly zone by burning tires in Aleppo.
Some are even apologizing to environmentalists.
"Of course this is going to effect the environment pollution, it's going to effect the ozone. ... We're very sorry. Please forgive us. But you have all turned your backs on the Syrian people," said a Syrian man in Aleppo.
The goal is to halt Russian and Syrian regime airstrikes.
Opposition-held east Aleppo is completely surrounded by the regime. Hundreds of thousands of people remain in the besieged area.
The regime and Russia have offered civilians passages out. But they all go to regime territory, and some civilians fear they could be imprisoned or killed.
Rebel groups are now trying to lift the siege with an offensive south of Aleppo. That includes the rebranded Al-Qaeda ally, Jabhat Fateh al-Sham.
