Homeland Security secretary has no plans to raise U.S. terror alert.
The Department of Homeland Security says Secretary Michael Chertoff is closely monitoring today's events in London. But a spokeswoman for the federal agency says Chertoff has no immediate plans to raise the U.S. terror alert. U.S. mass transit systems have remained on Code Orange -- or high alert -- since the London bombings two weeks ago, but the rest of the country is at yellow, signifying an elevated risk.
In Washington, subway trains and buses are said to be running normally today. But a Metro spokeswoman says passengers should expect to see bomb-sniffing dogs and increased patrols at train stations. Buses also might be randomly checked.
