The Cage: The fight for Sri Lanka & the Last Days of the Tamil Tigers is a book about the final stages of the Sri Lankan Civil War written by journalist and former United Nations official Gordon Weiss. Weiss was the UN's spokesman in Sri Lanka during the final months of the civil war. Since leaving the UN Weiss has been a vocal critic of the conduct of both the Sri Lankan military and the rebel Liberation Tigers of Tamil Eelam. Weiss believes that war crimes were committed during the final stages of the civil war and has called for an international investigation. According to Weiss up to 40,000 civilians may have been killed in the final stages of the civil war.
