'' Mosques , shrines and other religious sites have been destroyed , and members of different ethnic and religious groups have been persecuted , she said . `` The international community must intensify its efforts to protect all Iraqis , including ethnic and religious communities and those who are particularly vulnerable , '' Pansieri said .
