Protesters trying to reach the offices of the far-right party Golden Dawn have clashed with police on the streets of the Greek capital, Athens.
The unrest follows on from protests in several parts of Greece earlier in the month, which were sparked by the fatal stabbing of Pavlos Fyssas, 34. A Golden Dawn supporter was arrested by police, and allegedly admitted to the killing.
The BBC's Mark Lowen in Athens said that many protesters in Greece felt the government should have done more, and sooner, in response to Neo-Nazi activities.
