Tuesday's decision came after Saudi Arabia severed relations with Iran on Sunday after an attack on its embassy in Tehran following the kingdom's execution of Shia religious leader Nimr al-Nimr, who was put to death along with 46 other mostly Sunni convicts on terrorism charges, according to the report.
