The U.S. Embassy in Manila was closed to the public on Tuesday after receiving "plausible threat information," the embassy said in a statement.
The statement, posted on its Web site, did not elaborate. It said the embassy would resume all public operations, including visa operations, "when deemed appropriate."
Manila Radio DZMM reported that police operatives were inside the embassy compound along Manila Bay after a bomb threat Monday night, but officials did not comment immediately.
The embassy urged Americans in the statement "to remain aware of the continued potential for terrorist attacks against Americans, U.S. or other Western interests in the Philippines", AP reports.
