Bangladeshi soldiers so far recovered 10 bodies in a second mass grave in a military compound in the capital Dhaka on Saturday, an official told AFP, bringing the death toll from a deadly mutiny to 76.
Fire service operations chief Sheikh Mohammad Shahjalal said the operation was continuing and the number of bodies recovered was expected to rise.
"We have so far removed 10 dead bodies but there are still many more that we need to dig out. They are badly decomposed and many are mutilated," he said.
"We have to exercise extreme caution when removing these bodies because so many are disfigured. It's not just a matter of shovelling them out."
Rescuers on Friday uncovered a first mass grave in the military compound that contained 38 bodies, and Shahjalal said he feared the second grave was bigger.
Another 28 bodies have been recovered in other parts of the compound including in drains and sewers following a 33-hour revolt by rank-and-file border security troops that began early on Wednesday.
Most of the dead are senior military personnel.
