executed "with dignity"

At least 80 skeletons lie in a mass grave in an ancient Greek cemetery, their wrists clamped by iron shackles.
They are the victims, say archaeologists, of a mass execution. But who they were, how they got there and why they appear to have been buried with a measure of respect - that all remains a mystery....

"They have been executed, all in the same manner. But they have been buried with respect," Dr. Stella Chryssoulaki, head of excavations, said.
"They are all tied at the hands with handcuffs and most of them are very very young and in a very good state of health when they were executed."
