The war crimes tribunal today asked investigators to submit its report by April 30 on two Habiganj brothers suspected of committing wartime offenses during 1971.

International Crimes Tribunal-2 gave the order after its prosecutor Sultan Mahmud Simon sought one-month time to submit the report.

Earlier on March 11, the tribunal asked the prosecution to submit an investigation report, if there is any, today over the allegations against the suspected siblings.

Arrested on February 10, Mahibur Rahman Boromian, 70, former chairman of Baniachang upazila's Khagaura union parishad; and Majibur Rahman Angur Mian, 65, the incumbent chairman, have been kept in a jail.

The brothers allegedly formed the Razakar Bahini, the Pakistani occupation army's auxiliary force, in their area and used to hand over freedom fighters to the army.
