In the wake of an Iranian ballistic missile attack on air bases which house US forces in Iraq, the UN Secretary-General said on Wednesday that he would “continue his active engagement” to de-escalate tensions and avert full-scale war.

Iranian Foreign Minister says Iran informed the Iraqi government of its retaliatory attack on US bases, reaffirming Tehran’s respect for the sovereignty and territorial integrity of the Arab country.

The U.S. killing of senior Iranian military commander Maj. Gen. Qassem Soleimani left many of America’s allies in the Middle East confused and nervous. That includes Saudi Arabia, the top regional rival of Iran.
