Operation Poomalai (Pūmālai, lit. "Flower Garland"), also known as Eagle Mission 4, was the codename assigned to a mission undertaken by the Indian Air Force for airdropping supplies over the besieged town of Jaffna in Sri Lanka on 4 June 1987 to support the Tamil Tigers during the Sri Lankan Civil War. Jaffna was then under blockade by Sri Lankan troops as a part of Colombo's offensive against the Tamil separatist movement. Concerned over alleged violations of interests of the Tamils, who had broader support among the Tamil population of South India as well as the government, India attempted to negotiate a political settlement but the Indian offers had been rebuffed by Colombo. As civilian casualties grew, calls grew within India to intervene in what was increasingly seen in the Indian (and the Tamil) media as a developing humanitarian crisis, especially with reports of aerial bombardment against rebel positions in civilian areas. The Indian government, under Rajiv Gandhi, decided to attempt to deliver aid to the northern area of Sri Lanka as a symbolic act of support to the rebels. The first of those efforts, a naval flotilla, was intercepted by the Sri Lanka Navy and was ordered to withdraw. Two days later, India mounted the airdrop over Jaffna. Background The ethnic conflict in Sri Lanka can be traced to the independence of the island in 1948 from Britain. At the time a Sinhala majority government was instituted that passed legislation deemed discriminatory by the substantial Tamil minority population. In the 1970s two major Tamil parties united to form the Tamil United Liberation Front (TULF) that started agitating for a separate state of Tamil Eelam within the system in a federal structure in northern and eastern Sri Lanka that would grant the Tamils greater autonomy. Outside the TULF, however, factions advocating more radical and militant courses of action soon emerged, and the divisions started flaring into a violent civil war. The first round of violence flared in 1983 when the Four Four Bravo incident occurred, which sparked anti-Tamil riots in which nearly 3000 Tamil civilians were killed by state-sponsored mobs. The riots only aided in the deterioration of the already worsening ethnic strife. The militant factions, notably the LTTE, at this time recruited in large numbers and continued building on popular Tamil dissent and stepped up the guerrilla activities. In May 1985, the guerrillas launched an attack in Sri Maha
