"Blue" and "green" make Palestinians in Jerusalem suffer

“Palestinian and Israeli human rights groups have revealed that 20,000 children from Jerusalem are denied permission to live with their parents in the occupied city of Jerusalem because, the Israeli authorities say, one parent holds a West Bank ID card [“a green ID card”]. Apart from the mental anguish, this is causing great difficulty for these children with regards to their access to education and health services.” 

P.S: Palestinians living in Jerusalem hold a blue ID card issued by the occupying Israeli authorities.
