You can clearly see the fireworks being shot from inside the mosque, and not a hint of Israeli police. Yet the announcer says that the Palestinians are taking shelter to avoid "Israeli fire."
The police did fire flash bombs and people did run into the mosque - after this scene.
I've seen deceptive captions on photos before to tell people they are looking at something other than what they are seeing, but this is exceptionally egregious.
In a similar vein, here's a video of Jews visiting the Temple Mount this morning, the last day they will be allowed to do so this month. Palestinians are trying to intimidate the Jews by chanting slogans at them, and the Jews good-naturedly clap along, wave and even dance to the attempts at intimidation.
The caption at Al Qastal:
"Colonial Israeli settlers perform Talmudic prayers to provoke Palestinians during the storming of Jerusalem's Al-Aqsa Mosque"
See? Jews smiling and laughing at attempts to intimidate them is a provocation against the sensitive feelings of Palestinians!
