The exact details are appropriately murky but what we know is encouraging:
The arrest of an alleged al-Qaeda gang in Manchester and Liverpool said to be planning an Easter bombing campaign earlier this year led investigators to Najibullah Zazi in New York, sources say.
It is claimed he was part of a gang set to attack the New York subway using truck bombs or suicide bombers with the same explosives used on July 21 in London.
They had bought the ingredients for his bombs and he had allegedly filmed Grand Central Station on his mobile phone.
Security sources have told the Daily Telegraph that Zazi and the men arrested in Manchester were part of a complex network directed from Pakistan.
They are reticent on how Zazi was identified but admit it was through an “intercepted communication.”
The network was uncovered following the arrest of a US national, Bryant Neal Vinas, in Pakistan last November.
Now if we could just increase the level of cooperation and communication domestically.
