Indian Prime Minister Manmohan Singh on Tuesday dismissed talk of war with Pakistan but again demanded it act against militants blamed for Mumbai attacks. "The issue is not war. Nobody wants war. We would like an objective effort to dismantle terror infrastructure," Singh told reporters in New Delhi. Singh's comments followed similar remarks by Foreign Minister Pranab Mukherjee. "My request to our friends in Pakistan would be they should address the issue. "India has requested Pakistan to take action against perpetrators of these attacks." New Delhi has blamed last month's attacks, in which gunmen killed 163 people, on the banned Pakistan-based extremist group Lashkar-e-Taiba (LeT) which is fighting Indian rule in disputed Kashmir.
