Bangladesh's former prime minister Sheikh Hasina has denied committing crimes against humanity during a deadly crackdown on last year's uprising that ousted her, days before the special tribunal trying her is due to deliver a verdict.

Hasina is accused of being the main architect behind hundreds of killings during the mass protests against her autocratic rule - an allegation she denies.

In her first interview with the BBC since she fled the country on 5 August 2024, she said her trial in absentia was a farce orchestrated by a kangaroo court controlled by political opponents.

Prosecutors are seeking the death penalty for Hasina if she is found guilty on Monday.

Hasina claimed the trial was destined to deliver a pre-ordained guilty verdict. Security has been tightened in and around the tribunal in the capital Dhaka ahead of Monday's verdict.

It will mark a significant moment for the country as well as for the relatives of those killed during the student-led anti-government protests that ousted Hasina.

UN human rights investigators have said up to 1,400 people were killed when Hasina and her government used systematic, deadly violence against protesters in the failed bid to hold onto power.

The former prime minister has refused to return from India to attend the trial. She has been accused of personally ordering security forces to fire at protesters in the weeks before she fled.

In an email interview, Hasina told the BBC she categorically denied such allegations. I'm not denying that the situation got out of control, nor that many lives were lost needlessly. But I never issued any order to fire on unarmed civilians, she said.

Leaked audio of one of her phone calls verified by BBC Eye earlier this year suggested that she had authorised the use of lethal weapons in July 2024. The audio was played in court during the trial.

Hasina was formally indicted along with two others in July this year. They are former home minister Asaduzzaman Khan Kamal and former inspector general of police Chowdhury Abdullah Al-Mamun.

Lawyers representing her issued a statement on Monday saying they had filed an urgent appeal to the UN raising serious fair trial and due process issues at the International Crimes Tribunal in Bangladesh.

Hasina added her political opponents had gone after her in an attempt to liquidate her Awami League party as a political force. The Awami League is already banned from standing in general elections due in February.

The BBC interview also covered other serious allegations of abuses committed during Hasina's 15-year rule. After Hasina was ousted from power, a number of secret jails were discovered holding prisoners who had been detained for years without any legal process.

Hasina denied her involvement in alleged extra-judicial killings and disappearances, which rights groups say she was responsible for as the head of government during her leadership.

This is denied in terms of my own involvement, but if there is evidence of abuse by officials, let us have it examined properly in an impartial, depoliticised process, she said.

Hasina and other senior members of her former government are also facing trial for corruption in a separate court, charges they deny.
