CHICAGO, April 26: Four Pakistanis have been charged as co-conspirators in the 2008 Mumbai attacks that killed 166 people, including six Americans, US prosecutors said on Monday.

The four were previously mentioned, but not named, in indictments charging American David Headley and Pakistani-born Chicago businessman Tahawwur Rana with helping to identify targets in Mumbai.

Headley and Rana have also been charged in a plot to attack a Danish newspaper that was never carried out.

Headley pleaded guilty in March 2010 and is cooperating with US investigators about taking several trips to India --- and later to Denmark --- to scout targets for the coordinated and lethal assault. Rana has been held since his arrest in 2009 as a conspirator with Headley, and his US trial is scheduled to begin on May 16. His attorney was not immediately available for comment.

All of the four newly-indicted figures are linked to the Lashkar-e-Taiba, one of the largest and best-funded militant groups in the region. The group is blamed for the November 2008 attacks on Mumbai.

Those newly indicted were Sajid Mir, Abu Qahafa, Mazhar Iqbal, and a fourth defendant known only by the alias “Major Iqbal”. None are in US custody. All four are believed to be in Pakistan.

They were charged with six counts of aiding and abetting the murder of US citizens and other charges related to the Mumbai attacks and providing support to the Lashkar.

Mir was also charged in the plot against Denmark’s Jyllands-Posten newspaper aiming to revenge the publication of images of Prophet Mohammad (PBUH) that enraged many Muslims and prompted protests.

US Attorney Patrick Fitzgerald in Chicago had requested the superseding indictment handed up by a grand jury on April 21 charging the four to be sealed to give the government time to alert US agencies and consult with foreign authorities.—Reuters
