Iran’s foreign ministry has urged Iranian pilgrims to postpone their visits to Shiite holy sites in Iraq amid the turmoil in the neighboring Arab nation. Imam Hussein was killed in a climactic battle in Karbala in A.D. 680, which cemented the rift between Sunnis and Shiites. Iraq’s foreign ministry has summoned Iran’s ambassador to Baghdad to denounce his threat that Tehran would retaliate to an American attack anywhere in the world, including in Iraq.
