Police officers have gathered outside an Athens hospital, staging a silent vigil for a colleague.
About 700 police officers have gathered outside a hospital in Greece where a policeman is being treated following a shooting attack linked to a domestic terrorist group.
The 21-year-old officer was shot and seriously wounded in central Athens on Monday.
Police matched recovered bullet casings to a weapon used in the past by a far-left Greek militant group, Revolutionary Struggle.
The attack followed serious riots last month after the fatal shooting of a teenager by police.
Police officers on Tuesday gathered outside an Athens hospital, staging a silent vigil to support their wounded colleague. The wounded policeman remains in critical condition.
