Iran, one of the few countries involved in the Syria conflict not to have been affected by relentless terrorist attacks, woke up to a new reality on Wednesday, when armed men and perhaps one woman simultaneously staged attacks on the Parliament and on the landmark mausoleum of the founder of the Islamic Republic, Ayatollah Ruhollah Khomeini.

At least two people were killed and 35 others wounded in the assaults, according to the state-sponsored Iranian Students’ News Agency. While the Islamic State immediately issued a claim of responsibility, suspicions in Tehran were also directed at Saudi Arabia, Iran’s regional nemesis, newly emboldened by a supportive visit from President Trump last month.

Saudi Arabia recently raised the volume of criticism against Iran, and the country led a regional effort on Monday to isolate Qatar, the one Persian Gulf country that maintains relations with Tehran.
