A Pakistani Al-Qaeda suspect, who was extradited a week ago from Britain to the U.S., pleaded not guilty to plotting to send a suicide bomber to detonate explosives aboard the New York City subway system.
Abid Naseer, 26, who is also accused of participating in other plans for attacks in Norway and Britain, entered his not guilty plea in a Brooklyn federal court through his lawyer, Steven Brounstein, the federal prosecutor said.
The judge ordered Naseer to remain in detention until his next hearing on March 7.
The US justice department said in July that Naseer had been charged with conspiring to use weapons of mass destruction and to commit murder abroad, supporting Al-Qaeda, as well as "committing and attempting to commit an act of terrorism transcending national boundaries," among other counts, AFP reported.
Naseer was first arrested in 2009 in northern Britain in a counter-terrorism operation along with 11 other men suspected of preparing an attack against a shopping center in Manchester.
They were all released without charges, but he was then arrested for a second time in July 2010 at the request of Brooklyn prosecutors, who accused him of participating in the plot to attack the New York City subway in 2009.
In the federal indictment, Naseer is named co-defendant along with Bosnian-born American Adis Medunjanin, who was sentenced in November to life in prison for planning to detonate the explosives strapped to his body on the subway as revenge for American attacks in Afghanistan
Two other men in the alleged plot, high school friends of Medunjanin, pleaded guilty and testified against him and await sentencing later this year.
Naseer had done scouting for these attacks, but the plan unraveled when Medunjanin realized he was under surveillance and tried to dispose of the evidence.
According to AFP, Federal prosecutor Loretta Lynch called it one of the most serious plots since September 11, 2011, saying at Medunjanin's sentencing that "scores of innocent New Yorkers would have been killed or maimed had Medunjanin succeeded."
