2003 South Bhutan clashes
The August 2003 South Bhutan Clashes were a series of clashes between ULFA militants and unidentified gunmen in Southern Bhutan. The clashes left at least 11 people dead and dozens injured. While the incidents were scarcely reported at the time, many believe they were the first instances of Bhutanese strikes against ULFA militants in the country's south, and tensions between ULFA, allied Assamese separatist groups, and Bhutan would lead to a full-fledged conflict breaking out just four months later.
Background
In 1990, India launched Operations Rhino and Bajrang against Assam separatist groups, which caused the militants to relocate their camps to Bhutan. In the 1990s, ULFA and NDFB, two groups targeted by the Indian operations, allegedly assisted the government of Bhutan in expelling the ethnic Lhotshampa population and occupied the abandoned land.In 1996, Bhutan discovered a large number of camps on its southern border with India, which were set up by various separatist movements including ULFA, NDFB, BLTF, and KLO. These camps were used to train cadres and store equipment while allowing militants to launch attacks into Indian territory.
India exerted diplomatic pressure on Bhutan and offered support in removing rebel organizations from its soil. Bhutan initially pursued a peaceful solution and opened dialogue with militant groups in 1998. ULFA agreed to close down four of its camps in June 2001, but the Bhutanese government soon discovered that the camps had merely been relocated.
Furthermore, ULFA allegedly helped to create several militant groups in southern Bhutan with the help of Nepali Maoists, KLO, and the NDFB, including the BTF and BGLF. This caused Bhutan to become even more concerned and further justified an anti-Assamese separatist operation. Bhutanese parliamentarians began to propose raising the number of Bhutanese militia and introducing conscription, motions which were soon dismissed.
