This doesn’t appear to be one of those cry-wolf situations.
The United States on Thursday raised its terror threat level after British police said they had arrested more than 20 suspects in a major terrorist plot to blow up passenger jets flying between the United Kingdom and the United States.
The foiled plot was “intended to be mass murder on an unimaginable scale,” Metropolitan Police Deputy Commissioner Paul Stephenson said.
The intelligence that uncovered the plot “makes very strong links to al Qaeda,” a senior U.S. administration official told CNN.
As of now, the threat warning has been raised to “red” for commercial flights from Britain to the United States, marking the first time the warning system has reached this level (it designates a “severe risk of terrorist attacks”).
“To defend further against any remaining threat from this plot, we will also raise the threat level to high, or orange, for all commercial aviation operating in or destined for the United States,” Chertoff said.
A statement issued by Chertoff said “currently, there is no indication … of plotting within the United States.”
The emphasis appears to be on liquids as a means of carrying explosives onto a plane through carry-on luggage, and then mixed in-flight, suggesting a new area of scrutiny for air travelers.
Officials were requiring passengers to check everything except personal items like keys, wallets, and passports, which they had to carry in plastic bags. Drinks and other liquid items were banned.
Travelers were required to remove spectacles or sunglasses from their cases, and those traveling with infants were required to taste any baby milk in front of security officials.
Britain’s Department for Transport said it was requiring secondary searches of travelers headed for the United States, with a particular eye to removing any liquids they might have with them.
A U.S. administration official said the terror plot targeted Continental, United, and American Airlines. British Home Secretary John Reid said the plotters planned loss of life on “an unprecedented scale.”
I’m sure we’ll be hearing more throughout the day.
