U.S. Firms Heighten Security After Threat

American businesses in the emirate increased security precautions after an anonymous phone call to the U.S. Embassy warned of a possible attack on an “American location.” The U.S. Embassy issued a memorandum advising Americans in the Persian Gulf state to be cautious. Kuwait hosts about 8,000 Americans, including several hundred U.S. military personnel. The embassy memorandum came only days after a similar warning in Saudi Arabia. The U.S. Embassy there said it continued to receive reports of possible attacks against U.S. interests in the kingdom.
