In July 1987, faced with growing anger among its own Tamils and a flood of refugees, India intervened directly in the conflict for the first time by initially airdropping food parcels into Jaffna. After negotiations, India and Sri Lanka entered into the Indo-Sri Lanka Accord. Though the conflict was between the Tamil and Sinhalese people, India and Sri Lanka signed the peace accord instead of India influencing both parties to sign a peace accord among themselves. The peace accord assigned a certain degree of regional autonomy in the Tamil areas, with Eelam People's Revolutionary Liberation Front (EPRLF) controlling the regional council and called for the Tamil militant groups to surrender. India was to send a peacekeeping force, named the Indian Peace Keeping Force (IPKF), part of the Indian Army, to Sri Lanka to enforce the disarmament and to watch over the regional council.
