The investigating officer on Wednesday began testifying against retired Major General Ziaul Ahsan in a crimes against humanity case over the alleged enforced disappearance and killing of more than 100 people during the Awami League government.

The International Crimes Tribunal-1, headed by Justice Golam Mortuza, adjourned the testimony until Sunday after recording part of the investigating officer’s deposition.

Prosecutor Gazi M H Tamim said the officer would complete his testimony on Sunday, bringing the prosecution’s presentation of witnesses to an end.

The defence will then have the opportunity to call its own witnesses, if it chooses, before the case moves to closing arguments.

The prosecution filed formal charges against Ziaul on December 17 last year, bringing three counts over the alleged enforced disappearance and killing of more than 100 people.

The tribunal framed the charges on January 14 and ordered the trial to proceed.

Tamim said 15 witnesses had testified in the case so far.

“Through the testimony of 15 witnesses, we have been able to prove beyond reasonable doubt every charge that we brought against Ziaul Ahsan,” he said.

The claim represents the prosecution’s case before the tribunal, which has yet to reach a verdict.

Ziaul most recently headed the National Telecommunication Monitoring Centre, or NTMC, Bangladesh’s national telecommunications surveillance agency.

He was arrested in mid-August 2024, shortly after the fall of the Awami League government.
