This year a thousand Palestinians were honored by the king for their family members trying to murder Jews.
Fatah's Facebook page describes the reception as "A full reception with red carpets, roses and sweets for Palestinian martyr families as soon as they arrive in Mecca for the hajj as guests of the custodian of the two holy mosques, a reception befitting the sacrifices of their martyrs."
Saudi Arabia might not like Hamas very much, but it doesn't mean that it is against terrorism against Jews.
