The U.S. embassy in the Philippines has temporarily closed to the public because of a security threat.
Philippine officials say a bomb squad, including sniffer dogs, searched the embassy in Manila Tuesday, but nothing unusual was found. The embassy will remain closed on Wednesday.
The embassy did not specify the nature of the threat, but Philippine authorities say it was made by telephone.
The threat came as U.S. intelligence chief John Negroponte arrived in Manila to discuss anti-terrorism measures with Philippine officials.
A statement posted on the embassy's web page today also reiterated a travel warning urging Americans to remain aware of the continued potential for terrorist attacks against Americans or other western interests in the Philippines.
