There’s another thread on this with a constantly-updating Al Jazeera article that included a timeline of events which I pasted over there before It got too far down the page. I’ll paste it here too:
Timeline: How the unrest began
• Students began protesting last month when a controversial government job quota system that favoured children of war veterans was reinstated by the High Court.
• The government responded by shutting down universities and using the police and military to crack down on protesters.
• Prime Minister Sheikh Hasina imposed a nationwide curfew and cut off access to phones and the internet.
• Some 200 people, mostly students, were killed. Thousands were arrested.
• On July 21, Bangladesh’s top court stepped in, ruling that the quotas should be scaled back from 30 percent to 5 percent, with 3 percent for relatives of veterans.
• Last week, demonstrations resumed with protesters issuing new demands, including bringing justice and accountability for those killed and for Hasina to step down.
• The prime minister had pledged a strong response, calling the demonstrators criminals and saboteurs.
