"In the year 1983 several Muslim people (Miya origin) were brutally killed by Dayanath Sarma and eight other persons," he told reporters.
Multiple complaints were filed against Ali by several organizations for his remarks in the state. Bir Lachit Sena also filed an FIR against him at the Dispur police station.
Meanwhile, Assam Pradesh Congress Committee (APCC) General Secretary, Bobbeeta Sharma, had issued a show cause notice to Ali for his "communally provocative" comments.
