DOHA: The United States embassy in Qatar advised Americans there to “shelter in place” Monday, with other Western embassies echoing the warning after Tehran threatened to retaliate for US strikes on its nuclear sites. Qatar, which lies 190 kilometers (120 miles) south of Iran across the Gulf, is home to the US’s largest military base in the region, Al-Udeid. “Out of an abundance of caution we recommend American citizens shelter in place until further notice,” the US embassy said on its website. Britain and Canada later cited the US security alert in their own recommendations to nationals.

The US Embassy in Qatar has ordered Americans in the nation to 'shelter in place' as fears grow of an Iranian retaliation to the US strikes on Saturday night.

Qatar's foreign affairs ministry said the advisory does "not necessarily reflect the existence of specific threats".
