The U.S. Embassy in Qatar has advised American citizens to shelter in place until further notice, citing heightened caution amid escalating tensions between Iran and Israel. The warning follows U.S. airstrikes on three Iranian nuclear sites and Israel’s earlier attacks that killed top Iranian officials and civilians. Iran has since launched retaliatory strikes. With around 10,000 U.S. troops stationed at Qatar’s Al Udeid Air Base, the situation remains volatile, prompting the embassy to issue the alert without providing further details.
