A video of the Ukrainian flag flying over Donetsk appeared: who did it

The Ukrainian flag, which appeared in the sky above occupied Donetsk on the morning of September 9, was launched by Ukrainian defenders. It was seen by thousands of people in the occupied territory, while Russian invaders tried to shoot it down in panic.
The flag was launched in honor of the day of the city of Avdiivka. It flew in the direction of occupied Donetsk, the head of Avdiivka city Military Administration Vitaly Barabash said on the air of the TV marathon (to watch the video, scroll to the end of the news).
"Today is the 245th anniversary of the founding of Avdiivka. We started the day with the national flag in the sky. It flew towards Donetsk. We're already hearing interceptions, they're a bit furious about it. They tried to shoot it down. But the national flag is already flying over the Kyiv district of Donetsk," he said.
Local channels published a video showing the flag of Ukraine flying in the sky above the Kyiv district of occupied Donetsk in the morning.
