Two men have been arrested on suspicion of plotting a terrorist attack as they tried to buy guns, a grenade and other weapons, it has emerged.
One of the men, understood to be an U.S.-born Muslim from the Queens area of New York, is said to have bragged about his plan to attack a synagogue moments before police swooped.
The man, who is believed to have a record of drugs convictions, was allegedly trying to sell narcotics to finance the weapons purchase.
The men, both said to be 'homegrown' and of North African descent, were intercepted by anti-terror officers in New York late last night, police sources said.

The plot is not believed to be in retaliation for Osama bin Laden's killing by Navy SEALs last week as planning had already begun before his death, police sources said.
The case is to be prosecuted by the Manhattan district attorney's office, while law enforcement officials said the pair were expected to be charged under New York State's terrorism laws.
The investigation was allegedly lead by the NYPD's intelligence division, in an unusual move that didn't involve the FBI.
The Police department would normally work alongside the FBI in such cases and rarely be prosecuted in state court.
Under US state law, the term terrorism constitutes an act intended 'to intimidate or coerce a civilian population; [...] to influence the policy of a government by intimidation or coercion; or [...] to affect the conduct of a government by mass destruction, assassination, or kidnapping.'
Details of the arrest and intent of the two men as yet remain unclear.
