Hasina’s government and her Awami League party had alleged that the violent protests were initiated as a part of a conspiracy against the elected government. Hasina had accused the opposition Bangladesh Nationalist Party (BNP) of collaborating with Jamaat-e-Islami, an extremist group, to provoke violence across the country in order to bring regime change in the country as they could not win popular elections.

According to a source on the ground, the violence during the quota reform movement was used by the imperialist powers led by the US to orchestrate regime change in the country. They also claimed that the new regime would be used to undo the secular and progressive reforms initiated by the Hasina government during her four terms.

In January’s national elections in Bangladesh, Sheikh Hasina had won her fourth straight term as prime minister since 2009. This was her fifth term as prime minister in total. She was first elected as prime minister in 1996. The US had questioned the legitimacy of the last elections in January.
