Washington [US], December 20 (ANI): The US Department of State's Diplomatic Security Service, through its Rewards for Justice (RFJ) office, is offering a reward for information on the terrorist attack in Dhaka, Bangladesh that left US citizen Avijit Roy dead and his wife, Rafida Bonya Ahmed, seriously injured.

The Secretary of State has authorised a reward of up to USD 5 million for information leading to the arrest or conviction in any country of anyone involved in the murder of Roy and the attack on Ahmed.

On February 26, 2015, Roy and Ahmed, both Bangladesh-born US citizens, were visiting Dhaka to attend a book fair when they were attacked by assailants with machetes. Roy was killed and Ahmed survived with critical injuries.

"This investigation remains open, and we are seeking information that will assist law enforcement agencies in bringing to justice the perpetrators of this heinous terrorist attack," the US State Department said in a statement on Monday.

A total of six individuals were charged, tried, and convicted in Bangladesh. Two of the convicted conspirators, Syed Ziaul Haque (aka Major Zia) and Akram Hussain were tried in absentia and remain at large.

Two related groups have claimed responsibility. Ansarullah Bangla Team, an al-Qaeda-inspired terrorist group based in Bangladesh, claimed responsibility for the attack. Shortly thereafter, Asim Umar, the now-deceased leader of al-Qaeda in the Indian Subcontinent (AQIS), posted a widely circulated video claiming that AQIS followers were responsible for the attack on Roy and Ahmed, the statement added.

In 2016, the Department of State designated AQIS as a Foreign Terrorist Organization under Section 219 of the Immigration and Nationality Act, and a Specially Designated Global Terrorist under Executive Order 13224, which provides authority to sanction terrorists and those who support terrorists or terrorist acts.
