Thus LTTE engaged in military conflict with the Indian Army, and launched its first attack on an Indian army rations truck on 8 October, killing five Indian para-commandos who were on board by strapping burning tires around their necks. The government of India stated that the IPKF should disarm the LTTE by force. The Indian Army launched assaults on the LTTE, including a month-long campaign, "Operation Pawan" to win control of the Jaffna Peninsula. The ruthlessness of this campaign, and the Indian army's subsequent anti-LTTE operations, which included civilian massacres and rapes made it extremely unpopular among many Tamils in Sri Lanka.
