SANAA, Yemen — The State Department says the U.S. Embassy in Yemen has closed to the public over security concerns amid street violence and turmoil that is roiling the impoverished Arab country.

Monday's statements says the embassy will be closed for consular services "until further notice out of an abundance of caution" for the safety of employees and others coming to the embassy.

The decision came hours after a U.S. drone strike killed three al-Qaida members in the first such operation since the resignation of Yemen's embattled President Abed Rabbo Mansour Hadi and the country's Cabinet.

They resigned following days of political wrangling with Shiite Houthi rebels who overran the capital, Sanaa, in September and have since been expanding their power grab.
