Dhaka said it would investigate the botched rebellion, including the role of so-called “foreign” backers.

Bangladesh has ordered the establishment of a commission to investigate a failed paramilitary insurgency in 2009 and the subsequent crackdown, including the role of so-called “foreign” backers, the investigation chief said.

In February 2009, insurgents stole thousands of weapons from the headquarters of the Bangladesh Rifles (BDR) paramilitary force before going on a killing spree in the military camp.

The uprising spread quickly, with thousands of soldiers seizing weapons and swearing fealty to the mutineers.

The army suppressed the rebellion, killing 74 people, including 57 officers.

The violent rebellion shocked the entire South Asian nation. A previous official inquiry blamed years of pent-up anger among soldiers who felt their calls for pay rises and better treatment were being ignored.

Since her fall, families of soldiers killed in the violence have been calling for the investigation to be reopened. They have repeatedly accused Hasina, then newly elected, of orchestrating a plan to weaken the military to increase her own power in a country prone to coups.

Protesters also alleged that India was involved in the conspiracy. The claims are likely to anger New Delhi, which did not immediately respond to the accusations.

“Our aim is to determine whether any foreign entity was involved in the massacre as allegations of domestic and international conspiracy have been raised,” committee chairman ALM Fazlur Rahman told reporters on Thursday.

Hasina’s iron-fisted rule is said to be backed by New Delhi, and the 77-year-old Hasina remains in India, exacerbating tensions between the two countries.

On Monday, Dhaka said it had asked India Send Hasina back Facing charges of “massacre, killings and crimes against humanity”.
