"Let me be clear: this does not mean the threat is over. The investigation continues to follow all leads. In particular, we are remaining vigilant for any signs of planning within the U.S. or directed at Americans," said Secretary Michael Chertoff. "We are maintaining a heightened level of security for United Kingdom flights bound for the United States and have put in place added measures for these flights even beyond the normal ORANGE procedures. Additionally, we are maintaining our heightened level of security for all flights both domestically and internationally."
The U.K.'s terrorism threat level was changed from CRITICAL (an attack is expected imminently), to SEVERE (an attack is highly likely).
