Yes, that's right, it's two Greek churches firing fireworks at each other!
More from the BBC:
Every Easter Sunday on the small Greek island of Chios a fireworks war breaks out between two rival parishes.
In a bizarre but long-cherished local tradition, two Orthodox churches in the town of Vrodandos fire rockets at each other's churches - while services are held.
The objective is to hit the other church's bell, but many rockets go astray, causing locals to rush frantically for cover.
I might go to church if we got to shoot rockets!
