The US has reminded Pakistan of its “special” responsibility to bring perpetrators of 26/11 Mumbai terror attacks to justice and asked it to do so “urgently”.State Department spokesman Mark Toner told this at his daily news conference in Washington. However Mr Toner has refused to make any comment on the statement by Tahawwur Hussain Rana arguing this is sub-judice. Rana, the Pakistani Canadian accused in the Mumbai terror attack case, has earlier claimed before a court that he provided “material support” to the terrorists at the behest of the Pakistan Government and its spy agency ISI and not the terror group Lashkar-e-Taiba.
