Tahawwur Rana, 52, was convicted in June 2011 of conspiracy to provide material support in the plot against the Morgenavisen Jyllands-Posten newspaper and of providing material support to the Pakistan-based Lashkar-e Tayyiba-terror organization.
The move comes after the Pakistani government banned his group, Jamaat-ud-Dawa (JuD), a charity affiliated with Lashkar-e-Tayyiba (LeT) which India blames for last month's Mumbai attacks.
The acknowledgment came three days after Pakistani security forces raided an LeT camp near Muzaffarabad, the capital of Pakistani-controlled Kashmir, in the first sign of government action against Lashkar-e-Tayyiba since the three-day siege of India's financial capital.
