During the Pro-Palestinian demonstrations recently, pictures of watermelons have been seen and have been causing confusion as to what exactly the fruit has to do with the Palestine struggle but it isn't a new thing, it goes back to Israels military occupation of Palestine after the 1967 war.
Following the take over, the Israeli's didn't want it to be seen that they had taken over another nation so they banned the flying of the Palestinian flag so the Palestinians instead flew flags of Watermelons which just happened to be the same colours of their flag, red, white, green and black and became a substitute for the Palestinian movement.
Although laws restricting the flag no longer exist, the symbol has continued to be used and is usually accompanied with a message that says: 'This is not a Palestinian flag', although it is a representation of it
Following the latest Israel murder spree, the then British Home Secretary tried to ban the Palestinian Flag stating that it showed support for Hamas until someone with more brain cells pointed out that it was the Palestinian Flag and not the Hamas Flag which people were showing so she backed down and said that
Palestinian Flags should not be used if they are done to show support for Hamas but by then the use of Watermelons had taken off.
