Police in Greece have formally arrested and charged three men with being members of the November 17 guerrilla group blamed for the killing of 23 people over the past 27 years including U.S. and British diplomats.
One of the three is reported to have admitted killing a British military attaché in Athens two years ago on 8 June 2000.
The killing of Brigadier Stephen Saunders in a drive-by shooting was the last crime linked to the organisation.
A police spokesman named the three as brothers Christodoulos Xiros, 44 and Vassilis Xiros, 30, as well as their friend, Dionysis Gerogiadis, 26.
Prosecutors charged them with dozens of offences from first degree murder and attempted murder to bomb attacks, bank robberies and being members of an outlawed group.
If found guilty they face sentences from 10 years to life in prison. They were given three days to prepare their defence before examining magistrates rule on whether they should face trial.
Wearing flak jackets, they were taken from Athens police headquarters to the prosecutor's office while heavily armed police cordoned off a section of central Athens.
