Pakistan's commitment to terrorism as an instrument of state policy has not abated one bit, External Affairs Minister Sushma Swaraj told world leaders at the UN on Saturday and asked them how India can pursue talks with a nation that "glorifies killers" and allows the Mumbai attack mastermind to "roam free" with impunity.

In a hard-hitting retort to Pakistan, Swaraj said India has made many efforts to hold talks with Islamabad and the only reason New Delhi has called off dialogue is because of Pakistan's behaviour. "We are accused of sabotaging the process of talks. This is a complete lie. We believe that talks are the only rational means to resolve the most complex of disputes," she said in her address to the General Debate of the 73rd session of the UN General Assembly here.
