Why did the situation escalate last week, resulting in so many deaths and injuries?

Following violent clashes between student protesters and Bangladesh Chhatra League (BCL) activists at different public universities around the country, celebrities have voiced their support for the quota reform movement. The July 15 incident left approximately 300 people injured, including female students and BCL members. As of July 17 (3:00pm), six fatalities have been reported due to the ongoing unrest.
