On 8 January 2020, in a military operation code named Operation Martyr Soleimani (Persian: عملیات شهید سلیمانی), Iran's Islamic Revolutionary Guard Corps (IRGC) launched over 12 ballistic missiles at the al-Asad Airbase in Al Anbar Governorate, western Iraq, as well as another airbase in Erbil, in response to the assassination of Major General Qasem Soleimani by a United States drone strike. The strike was the largest ballistic missile attack ever against U.S. forces abroad.
