Bangladesh is launching a manhunt for about 1,000 border guards who have fled their base after a mutiny in which more than 80 officers were killed.
Sheikh Hasina, the prime minister, said on Sunday that she has ordered the army to begin 'Operation Rebel Hunt' to find those responsible for the outbreak at the Bangladesh Rifles (BDR) headquarters in the capital, Dhaka.
Army units will be deployed across the country from Monday, Hasina told parliament, adding that she is seeking help from US and British police investigators.
"I have had discussions with [US Assistant Secretary of State] Richard Boucher. I told him I want FBI [Federal Bureau of Investigation] assistance in the probe," she said.
"I'd also like Scotland Yard [British investigators] to help us, and I have already sought UN support."
Nearly 670 BDR guards were under arrest, she said.
The prime minister's order came as security forces and emergency relief teams continued their search for bodies at the BDR headquarters.
The corpses of army officers at the compound, including the base's chief and his wife, were found buried in mass graves and stuffed down drains following the revolt.
Search continues
At least 70 officers remain missing after last Thursday's 33-hour mutiny, in which 9,000 guards rose up against their army leaders.
The guards' revolt against senior officers, reportedly launched over poor pay and conditions, ended after Hasina met a group of BDR troops and threatened to put down the revolt by force.
Hasina initially said that those who surrendered during the siege would be granted amnesty, but she later said those who committed murder would face punishment.
Those found guilty of plotting the revolt would be hanged, said Nabojit Khisa, a police station chief in Dhaka.
'Guilty to be hanged'
Several hundred soldiers have reported to the BDR headquarters in Dhaka, after a deadline was set for them to return to barracks.
"I've been in hiding for four days because I was worried about the consequences of this … I am stunned at how barbaric the killings were. When I heard gunshots I fled out the door in civilian dress," Hossain, a BDR guard, told the AFP news agency.
Syed Ashraful Islam, a local government minister, said that a special tribunal would be set up to try the accused.
The mutiny was apparently sparked soon after army officers rejected appeals for the BDR guards to have increases in pay, food subsidies and holidays.
