Civil war was raging in Sri Lanka and on 5 June 1987, India, with Operation Poomalai, intervened.

This came to light when a Sri Lankan naval officer named Vijitha Rahana tried to assault Rajiv Gandhi while he was visiting Colombo on 30 July, 1987. | Express PhotoThough the Indian Peace Keeping Force was not intended to get involved in major operations, but it ended up fighting large-scale military battles against the Liberation Tigers of Tamil Eelam.
