An explosion occurred at a US-led coalition base near Baghdad International Airport late Tuesday, just one day before Iranian President Masoud Pezeshkian's scheduled visit to Iraq. Iraqi security officials reported that two Katyusha rockets were involved, targeting a logistics support site used by international coalition advisers; however, the origin of the explosion remains undetermined, and no group has claimed responsibility. The incident, which has not disrupted air traffic, is under investigation amid rising tensions, as Iranian-backed militias have previously targeted US forces in the region. Kataib Hezbollah distanced itself from the attack, suggesting it was intended to disrupt the Iranian president's visit. This visit marks Pezeshkian's first official trip abroad since taking office in July, highlighting the close political ties between Iran and Iraq.
