Almost 100 people were reportedly killed on Sunday as student demonstrators demanding the prime minister’s resignation battled with police and ruling party activists.
The country’s largest Bengali-language daily newspaper, Prothom Alo, reported that at least 95 people were killed in the violence.
To quell the violence, the interior ministry ordered an indefinite national curfew, which took effect at 6 p.m. local time (12 p.m. GMT).
Internet connections were also suspended, and social media apps Facebook and WhatsApp were unavailable.
The latest turmoil comes after at least 200 people were murdered and thousands injured during student protests last month.
At least 10,000 other people were arrested.
The Supreme Court has now reduced the quota system.
However, students have returned to the streets, demanding Prime Minister Sheikh Hasina’s resignation and justice for those killed.
