Islamabad, Feb. 11 : The Pakistan Government on Wednesday registered a case against Mohammed Ajmal Amir Kasab, the lone terrorist captured alive during the November 26, 2008 Mumbai terror attack.

Media reports said that the charges were filed against Kasab and 13 other people on the basis of a Federal Investigation Agency (FIA) probe into the Mumbai attacks.

Islamabad ordered the FIA probe after India alleged that the Mumbai attacks were plotted in Pakistan.

Currently, Kasab is in the custody of Mumbai police.

Wednesday''s development came three days after Pakistani Intelligence agencies claimed that they had arrested three men for their alleged links to Kasab.

The Daily Times quoted sources in Karachi as saying that the Federal Investigation Agency in collaboration with other intelligence agencies had detained the three men from different parts of the city for their alleged association with Kasab.

The detainees were reportedly taken to Islamabad where they are reportedly being interrogated.

Earlier a private TV channel had claimed that the Pakistani dossier on the Mumbai terror attacks was ready and the PPP-led Government would file cases against five Pakistanis, including Ajmal Kasab, for planning the attacks.

The Interior Ministry's report into the Mumbai carnage is speculated to state that the attacks were not planned in Pakistan or India, but in a European country.

They also said that cases would be filed against five Pakistanis, including Kasab, for planning the Mumbai attacks.

"The conspiracy was hatched outside Pakistan. But Kasab and his accomplices used Pakistan territory by using Internet lines of the country. But no Pakistani official was involved. There will be legal action against Kasab and others in Pakistan. Pakistan may also want access to Kasab for investigation."

The Defence Committee of the Cabinet (DCC) met on Monday and reviewed the investigation report prepared by the Pakistani authorities on the information provided by India on Mumbai attacks. (ANI)
