Kokkadichcholai massacre: The Sri Lankan Army massacres 152 minority Tamil civilians in the village of Kokkadichcholai near the Eastern Province town of Batticaloa.

On June 12, 1991, 152 minority Sri Lankan Tamil civilians were massacred by members of the Sri Lankan military in the village Kokkadichcholai near the eastern province town of Batticaloa. The Sri Lankan government instituted a presidential commission to investigate the massacre. The commission found the commanding officer negligent in controlling his troops and recommended that he be removed from office, and identified nineteen other members of the Sri Lankan military to be responsible for mass murder. In a military tribunal that followed in the presidential commission in the capital city of Colombo, all nineteen soldiers were acquitted.

The Sri Lanka Army is the oldest and largest of the Sri Lanka Armed Forces. The army was officially established as the Ceylon Army in 1949, though the army traces its roots back in 1881 when Ceylon Light Infantry Volunteers was created; the army was renamed as the 'Sri Lanka Army' when Sri Lanka became a republic in 1972. In 2024, the Army had approximately 150,000 personnel.

The Tamils, also known by their endonym Tamilar, are a Dravidian ethnic group who natively speak the Tamil language and trace their ancestry mainly to the southern part of the Indian subcontinent. The Tamil language is one of the longest-surviving classical languages, with over two thousand years of written history, dating back to the Sangam period. Tamils constitute about 5.7% of the Indian population and form the majority in the South Indian state of Tamil Nadu and the union territory of Puducherry. They also form significant proportions of the populations in Sri Lanka (15.3%), Malaysia (7%) and Singapore (5%). Tamils have migrated world-wide since the 19th century CE and a significant population exists in South Africa, Mauritius, Fiji, as well as other regions such as the Southeast Asia, Middle East, Caribbean and parts of the Western World.
