British terrorist turning 'supergrass' nails Al Qaeda member over New York subway plot

London, May 2 (ANI): An Al Qaeda member, responsible for a suicide bomb attack on the New York subway system, has been convicted following a testimony from a British terrorist.

Adis Medunjanin, 28, a Bosnian-born US citizen, was found guilty after Saajid Badat, who was convicted in the UK in 2005, admitted his involvement in the plot to take a 'shoe bomb' on board in a transatlantic flight.

Medunjani was found guilty on Tuesday of all nine counts against him including conspiracy to use weapons of mass destruction and conspiracy to provide material support to Al Qaeda. He will be sentenced on September 7 when he faces a possible sentence of life imprisonment, The Telegraph reports.

Although Badat, 33, never met Medunjanin, but his testimony was deemed crucial by US prosecutors.

He reportedly had his 13-year sentence reduced by two years after agreeing to turn 'supergrass' and co-operate with the US and British authorities in revealing the Al Qaeda terrorist's name.

During his two-and-a-half-hour testimony recorded by the US court, Badat revealed details about the training methods used by Al Qaeda and testified about individuals who ran the camps, which tallied with the information given by two of Medunjanin's accomplices, Najibullah Zazi and Zarein Ahmedzay.

Zazi and Zarein, both 27, had previously pleaded guilty in the Subway bomb plot and were already testifying against Medunjanin, at Brooklyn Federal Court in New York.

The three had reportedly travelled to Pakistan initially to train for the attack and had planned to detonate their suicide bombs just days ahead of the eighth anniversary of the Sept. 11, 2001, terror attacks. (ANI)
