WASHINGTON (AP) — State Department spokeswoman Marie Harf says an unspecified number of U.S. embassies and consulates around the globe will be closed Sunday due to security concerns.

Harf says Thursday that it's a precautionary step, taken out of an "abundance of caution" because of unspecified information indicating a threat to U.S. facilities overseas. She says the diplomatic facilities may stay closed for more than a day, depending on analysis of the threat information.

Harf would not give a geographic location or say whether the information was related to terrorism. But she did point out the administration issued guidelines in February on potential terrorist threats around the world.

The last major warning came last fall when embassies warned American diplomatic facilities across the Muslim world of potential violence around Sept. 11.
