When a widespread armed insurgency broke out in Pakistan's Balochistan province in 1973, Iran, fearing the Baloch insurgency might spill over into its own Sistan and Baluchistan Province, offered large-scale support. Iran provided Pakistan with military hardware (including thirty AH-1 Cobra attack helicopters), intelligence, and $200 million in aid. The government of then-Pakistani Prime Minister Zulfikar Ali Bhutto declared its belief that, as in the 1971 Bangladesh Liberation War, India was once again behind the unrest and uprising of rebels in the Balochistan region. However, the Indian government denied any involvement, and claimed that it was fearful of further balkanisation of the subcontinent. After three years of fighting the uprising was majorly suppressed.
