The BBC:
A plot to blow up planes in flight from the UK to the US and commit "mass murder on an unimaginable scale" has been disrupted, Scotland Yard has said.
It is thought the plan was to detonate explosive devices smuggled in hand luggage on to as many as 10 aircraft.
Shortly after:
Heathrow airport has been closed to all incoming flights that are not already in the air. Flights in and out of Gatwick have been suspended.
One of the busiest airports in the world has been shut down!

Michelle Malkin comments:
Well, this certainly puts that appalling BBC satire, "The Terrorism Awards," making fun of planes crashing into buildings, in its place, doesn't it? Are they laughing at the BBC now.
She has a lot more at this post.
Brendon Loy has a massive post with numerous updates.
Captain Ed:
The reports are still sketchy, but the operation looks to have come to MI-5's attention some time ago, and that they waited until it went active to pull the trigger. The British had coordinated with American security officials, and the US raised the threat level for British inbound flights to our highest level, the first time international flights have received that threat indicator. MI-5 believes that the terrorists targeted flights to the US.
Update
Foreign Dispatches:
One wonders when all the "disproportionate response" bleaters and hand-wringers will get the message: safety against murderous Islamists cannot be secured at home by protecting murderous Islamists abroad, but by working to ensure that fanatical Islam is crushed everywhere it raises its head.
The Telegraph via Western Resistance:
Police have arrested 21 people in connection with the terrorist plot to blow up aircraft in mid-air, Paul Stephenson, the Metropolitan Police Deputy Commissioner said.
The majority of the arrests were in London with some in the Thames Valley and Birmingham and searches are ongoing at a number of addresses, he added.
[...] Sources indicated that the majority if not all of those arrested were British.
Stephen Taylor:
The hubs of the attacks were to be Heathrow airport, Birmingham and Manchester. Heathrow is the busiest international airport in the world (about 186,000 per day, 1.3 million passengers per week). Severe delays are to be expected.
Currently at the end of the post:
AP reports that targeted airplanes were to arrive in New York, Washington and California.
