US Embassies Issue Alerts as Iran Threatens Expanded War

U.S. embassies across the Middle East issued security alerts on Sunday, September 21, 2026, warning American citizens of potential travel disruptions and the "potential for unforeseen escalation" due to regional tensions. The alerts, sent to citizens in Israel, Saudi Arabia, Iraq, Kuwait, Lebanon, Jordan, Bahrain, the United Arab Emirates, and Qatar, cited ongoing fighting between Saudi Arabia and Iranian-backed Houthi militants in Yemen, noting the conflict "has the potential to escalate rapidly." The warnings came as Iran issued a stark threat of retaliation. A spokesman for Iran's Islamic Revolutionary Guard Corps warned that any new U.S. assault would be met with a change in "weaponry and the geography of the war." Separately, Iran's Khatam alAnbiya military headquarters warned that regional countries could be treated as "complicit" if they allow U.S. attacks from their bases, stating that "any mistake will result in painful attacks." President Trump, in an interview with Fox News on Sunday, said he is in "deciding mode" on Iran, considering options ranging from "wiping Iran out" to striking a deal.
