Start of Operation Pawan by Indian Peace Keeping Force in Sri Lanka that killed thousands of ethnic Tamil civilians and hundreds of Tamil Tigers and Indian Army soldiers.
Operation Pawan (Hindi: ऑपरेशन पवन Ŏparēśan Pavan, lit. "Operation Wind") was the code name assigned to the operation by the Indian Peace Keeping Force (IPKF) to take control of Jaffna from the Liberation Tigers of Tamil Eelam (LTTE), better known as the Tamil Tigers, in late 1987 to enforce the disarmament of the LTTE as a part of the Indo-Sri Lanka Accord. In brutal fighting lasting about three weeks, the IPKF took control of the Jaffna Peninsula from the LTTE, something that the Sri Lankan Army had tried but failed to do. Supported by Indian Army tanks, helicopter gunships and heavy artillery, the IPKF routed the LTTE at the cost of 214 soldiers and Officers.
