The explosions in Iran that killed almost 100 people at a ceremony to commemorate Qasem Soleimani’s death have prompted Iranian leaders to vow revenge. First Vice President Mohammad Mokhber stated that “a very strong retaliation will be handed to them on the hands of the soldiers of Soleimani.” Tehran has blamed the explosions on “terrorists,” but no group has claimed responsibility. State TV showed crowds gathering in Soleimani’s hometown, chanting “Death to Israel” and “Death to America.” Mass protests have been called for the funerals of the victims. The United States denied involvement in the explosions and said they appeared to be a “terrorist attack” similar to those carried out by ISIS. Iran has accused the US and Israel of backing anti-Iran militant groups. The previous attacks by ISIS in Iran included a deadly attack on a Shi’ite shrine in 2022. The assassination of Soleimani in 2020 and Iran’s retaliation brought the US and Iran close to full-blown conflict. The tensions between Iran and Israel, along with its ally the United States, have escalated due to various events in the Middle East.
