Fifteen Saudi Shia sentenced to death for 'spying for Iran'

A Saudi Arabian court has sentenced fifteen Saudi Shia to death. In Islam there are two big groups. They are Sunni and, Shia. They are both Islam but they are still different.  For example Catholics, and Mormons are both christian, but they are separate. Although, Muslims both hate Christians many would rather be forced to be friends with a Christian than the opposing form of Islam. In Saudi Arabia minority groups are constantly persecuted. At least 30 of them were Shia-Muslim, and they were accused of spying on the military, and passing on information to Iran, a Shia majority nation.
