The main suspect in the alleged attempt to set off a car bomb in New York's Times Square has admitted weapons and terrorism charges.
Faisal Shahzad was arrested at New
York's JFK airport on a flight to Dubai
Faisal Shahzad is accused of receiving funds and training from the Taliban in Pakistan to carry out the plot.
The Pakistani-born US citizen pleaded guilty to all charges in a Manhattan's Federal District Court.
A petrol and propane bomb was left in a sports utility vehicle near Broadway theatres on 1 May but failed to ignite.
As he entered a guilty plea for the first of 10 charges, Mr Shahzad said he wanted to plead guilty to all the charges.
He told the judge he wanted to "plead guilty and 100 times more".
He also warned that unless the US left Islamic countries "we will be attacking US".
Mr Shahzad, 30, was arrested two days after the bomb was discovered as he tried to take a flight to Dubai from New York's John F Kennedy airport.
He co-operated with investigators for two weeks, waiving his rights that protect arrested suspects from incriminating themselves, before requesting a lawyer, justice officials say.
The most serious charges against Mr Shahzad, including attempted use of a weapon of mass destruction and attempted act of terrorism transcending national boundaries, carry mandatory life sentences.
'Bomb-making training'
The indictment says Mr Shahzad admitted receiving bomb-making training in Pakistan, buying a 1993 Nissan Pathfinder SUV, loading it with gasoline, propane, fireworks and fertiliser, and attempting to blow it up in Times Square.
During their investigation, the FBI traced the purchase of the vehicle to Mr Shahzad, a transaction that eventually led to his arrest.
While being interrogated, Mr Shahzad revealed that he had gone to Pakistan's North Waziristan tribal region in December 2009 for bomb training with militants affiliated with the Pakistani Taliban, according to the indictment.
He is also alleged to have received about $5,000 in cash from an identified co-conspirator in Pakistan, whom he understood worked for the Taliban.
It said the same co-conspirator directed a second payment to Mr Shahzad, of $7,000 in April, with which he bought a weapon, material to make the car bomb and the Nissan Pathfinder.
"The facts alleged in this indictment show that the Pakistani Taliban facilitated Faisal Shahzad's attempted attack on American soil," Attorney General Eric Holder said after Mr Shahzad was indicted by a grand jury.
BBC security correspondent Gordon Corera says the increased US-led drone missile strikes in Pakistan and Afghanistan may have reduced the capacity of jihadists to carry out complex attacks abroad.
However, he says in the past two years, the US has seen increasing signs it is not immune to home-grown radicalisation.
