How did the watermelon become a symbol of Palestinian solidarity?
The use of the watermelon as a Palestinian symbol is not new.
It first appeared after the Six Day War in 1967, when Israel took control of the West Bank and Gaza and annexed East Jerusalem. At the time, the Israeli government made the public display of the Palestinian flag a criminal offense in Gaza and the West Bank.
So to avoid arrest or prosecution, Palestinians started using watermelon because, when cut, this fruit bears the national colors of the Palestinian flag. These colors are red, black, white and green.
