Islamabad, Sep 11 - Pakistani Interior Minister Rehman Malik Friday challenged India to a 'debate' during the upcoming session of UN General Assembly its probe into the 26/11 Mumbai terror attacks.

Talking to reporters here, Malik asked India to stop the blame game and resume talks with Pakistan.

Malik's remarks came a day after India Thursday conveyed to the US its displeasure over Pakistan's reluctance to take action against militants arrested for their role in the Mumbai terror attacks and letting their mastermind go free.

Indian Home minister P. Chidambaram, who met Secretary of State Hillary Clinton, other government officials and key lawmakers on his second day in Washington, said he was overall 'pleased with the level of interest shown by the officials and leaders of the US administration to the security issues that confront India'.

Addressing the media after the talks, Chidambaram said he had briefed US leaders on the quick progress made in the Mumbai terror trial and Pakistan's reluctance to take action against five to six militants arrested for role in 26/11 and releasing their mastermind Hafiz Saeed.
