The State Department said Tuesday that the U.S. Embassy in Yemen has reopened, two weeks after being evacuated in response to what the Obama administration said was a serious terrorist threat.

The department said the embassy reopened Sunday and would provide “limited public services.”

The embassy in Sanaa, the Yemeni capital, was the only one that had remained closed of 20 embassies and consulates in the Middle East and North Africa shut down early this month after intelligence officials said they had intercepted threats to the U.S. facilities.

Britain, France and Germany, which had also closed their embassies in Yemen, reopened them Sunday as well.

The administration offered no information on the status of the threat, which in Yemen was said to have been intercepted in a communication between Ayman al-Zawahiri, the Pakistan-based leader of al-Qaeda, and a Yemen-based affiliate, al-Qaeda in the Arabian Peninsula.

The United States has launched 22 drone strikes against alleged terrorist targets in Yemen this year, according to a tally by the New America Foundation, including eight since Aug. 1.
