WASHINGTON (AP) — The U.S. has temporarily closed its embassy in Yemen, officials said Wednesday, citing recent attacks against Westerners in the capital of Sanaa but no specific threats to Americans.

State Department deputy spokeswoman Marie Harf said the U.S. Embassy in Sanaa would reopen “once it is deemed appropriate.” She described the closure, which affects U.S. services to the public like visa processing, as precautionary.
