What accusations were made against Sheikh Hasina's administration by the UN Human Rights office?

According to Shafiquull Alam, press secretary for Mohammed Yunus, the United Nations High Commissioner for Human Rights (OHCHR) has accused Sheikh Hasina's administration of committing crimes against humanity. This serious allegation appears in a report cited by the press secretary during his statement. Following this UN report and accounts from other rights groups, there has reportedly been increasing pressure on India to return Sheikh Hasina to Bangladesh. The accusations have significant implications for Bangladesh's political landscape and potentially for international relations, particularly with India where Hasina has presumably taken refuge.
