英國政府本（10）日宣佈破獲了一起企圖炸毀從英國飛到美國航班的恐怖襲擊陰謀，所有自國外飛往英國的班機幾乎全面取消。英國主管機關已立即將反恐警戒狀態從「嚴重（severe）」升高到「危急（critical）」的最高狀態，以防範恐怖份子攻擊。英國警方表示，據已知陰謀顯示，恐怖分子企圖通過手提行李把爆炸裝置帶上飛機，然後在飛行中途引爆，目標是炸毀多架飛往美國的班機；被逮捕的21名嫌犯，大部份位在倫敦，警方正積極循線全面擴大追查。
針對此一恐怖襲擊陰謀，英國內政部及運輸部於本（10）日發布新聞稿及「旅遊告示：加強安全措施(Advice to travelers-increased security measures)」，要點如下：
＊ 英國機場已全面加強安全檢查，所有乘客客都必須接受搜身，包括鞋襪及所有物品都必須接受X光檢查。

UK threat level increased to critical 10 August 2006
The UK threat level has been increased to critical following the disruption of a major terrorist plot to target UK flights.
Following this morning's police action, security at all UK airports has been increased and additional security measures have been put in place for all flights.
The Department for Transport has issued important travel advice to anyone travelling from a UK airport.
Home Secretary's statement
John Reid, the Home Secretary, issued the following statement on this morning's police action: 'Overnight the police, with the full knowledge of Ministers, have carried out a major counter-terrorism operation to disrupt what we believe to be a major threat to the UK and international partners.
The police, acting with the Security Service MI5, are investigating an alleged plot to bring down a number of aircraft through mid-flight explosions, causing a considerable loss of life.
The police believe the alleged plot was a very significant one indeed.
At 2am this morning the Joint Terrorism Analysis Centre raised the UK threat state to its highest level – "Critical"
This is now being publicly announced, as I promised to Parliament last month.
This is a precautionary measure. We are doing everything possible to disrupt any further terrorist activity. This will mean major disruption at all UK airports from today.
But as far as is possible we want people to go about their business as normal.
The police will provide an update on the operation later this morning and Ministers will keep the public regularly informed.'
• Advice if you're travelling today
Advice to travellers - increased security measures
10 August 2006
Due to the increased security measures currently in place at UK airports, the following advice to anyone travelling today has been issued by the Department of Transport. With immediate effect, the following arrangements apply to all passengers starting their journey at a UK airport and to those transferring between flights at a UK airport.
Flying today
• contact the airline you're flying with to check your flight is still going ahead
• arrive as early as possible for your flight to ensure that, other than the few permitted items listed below, all your belongings are placed in your hold baggage and checked in
• expect long delays
Hand luggage
All cabin baggage must be processed as hold baggage and carried in the hold of passenger aircraft departing UK airports.
The only items that may be taken through airport security search points and in to the cabin, in a single (ideally transparent) plastic carrier bag, are the following:
• pocket-size wallets and pocket-size purses plus contents (for example money, credit cards, identity cards, etc - handbags are not allowed.
• travel documents essential for the journey (eg, passports and travel tickets)
• prescription medicines and medical items sufficient and essential for the flight (eg, diabetic kit), except in liquid form unless verified as authentic
• spectacles and sunglasses, without cases
• contact lens holders, without bottles of solution
• for those travelling with an infant: baby food, milk (the contents of each bottle must be tasted by the accompanying passenger) and sanitary items sufficient and essential for the flight (nappies, wipes, creams and nappy disposal bags)
• female sanitary items sufficient and essential for the flight, if unboxed (eg, tampons, pads, towels and wipes)
• tissues (unboxed) and/or handkerchiefs
• keys (but not with electrical key fobs)
Nothing may be carried in pockets.
Searches and x-ray screening
All passengers must be hand searched, and their footwear and all the items they are carrying must be x-ray screened.
Pushchairs and walking aids must be x-ray screened, and only airport-provided wheelchairs may pass through the screening point.
Flying to the USA
The US has raised its threat level to 'red' for flights coming in from the UK. This means passengers are likely to encounter additional security measures once they land at an American airport.
In addition to the security measures listed above, all passengers boarding flights to the US and all the items they are carrying, including those acquired after the central screening point, must be subjected to secondary search at the boarding gate. Any liquids discovered will be removed from the passenger.
There are no changes to current hold baggage security measures.
Delays are inevitable
Regrettably, these additional security measures will mean significant delays at airports are inevitable.
The measures will make travel more difficult for passengers, particularly at such a busy time of the year. But they are necessary and will continue to keep flights from UK airports properly secure. We hope that these measures, which are being kept under review by the government, will need to be in place for a limited period only.
In light of the threat to aviation and the need to respond to it, we are asking the traveling public to be patient and understanding and to cooperate fully with airport security staff and the police.
If passengers have any questions on their travel arrangements or security in place at airports they should contact their airline or carrier.
Heathrow closed to incoming flights
Due to increased security measures that have caused considerable congestion at Heathrow Airport - London's main airport and the busiest airport in Europe - it has been closed to all incoming flights that are not already in the air.
Advice from Heathrow's operator BAA is that passengers should not come to Heathrow Airport today unless there journey is absolutely necessary.
If passengers must come to the airport today, BAA advise:
• travel to the airport by public transport
• arrive as early as possible for your flight
• expect very long delays
Heathrow - BA short-haul flights cancelled
All incoming and outgoing British Airways short-haul flights, scheduled for departure until 2.00pm have now been cancelled.
Stansted - Ryanair flights cancelled
Ryanair flights leaving London Stansted airport between 9.35am and 12.05pm have been cancelled.
Disruption to flights into Britain
Some flights into Britain have also been cancelled: • Brussels to London airports
• Lufthansa to all UK airports
• Olympic airlines to UK airports
• Air France, Paris to London
