Britain and the United States have warned of an imminent attack in Kuwait. The embassies of both NATO countries have warned their nationals in Kuwait that Al Qaida-aligned insurgents were preparing an imminent strike in the sheikdom. The embassies called on their citizens to be vigilant and lower their profile. "The embassy is issuing this message because it has credible information that terrorist groups are developing near-term plans for attacks against unspecified targets in Kuwait," the U.S. embassy said in a Dec. 14 warden message. "The embassy reminds all U.S. citizens to exercise caution, maintain a low profile and avoid areas where Westerners are known to congregate.""From time to time, the U.S. embassy in Kuwait may restrict the travel of official Americans or suspend public services for security reasons," the warden message added.
