Indian PM Manmohan Singh on Tuesday said Pakistan using terrorism as state policy and whipping up war hysteria. The Mumbai attacks must have had support from some official agencies within Pakistan, Singh told a security conference in New Delhi. "The terrorist attack in Mumbai in November last year was carried out by the Lashkar-e-Taiba." Manmohan Singh said foreigners had been targeted in the Mumbai attacks to convey instability in India. Manmohan Singh said that most of the terrorists act in connivance with intelligence agencies in neighbouring countries. While commenting on the challenges faced by India, the Indian Prime Minister said that problems faced by our country are compounded by vulnerable security environment and fragile governments in the neighbouring countries.
