Iraq Christians get Islamic State's warning they face death if they do not embrace Islam or pay special tax

The Islamic State group has threatened Christians in the Iraqi city of Mosul with death if they do not convert to Islam or pay a tax, Al Jazeera has learned.

The Sunni rebel group issued the orders in a letter after Friday prayers. The document, obtained by Al Jazeera, states that the order was issued after Christian leaders failed to attend a meeting called by the group.
