Bangladesh Prime Minister Sheikh Hasina has hit out at Pakistan, saying its Army launched a 'heinous' military operation in 1971 which triggered a 'genocide' during the liberation war, killing three million innocent people. In her address to the UN General Assembly on Thursday, Hasina said her country's parliament had recently declared March 25 as 'Genocide Day' to pay homage to the victims.
