Anger over the fatal shooting of a Greek schoolboy by a policeman has spread across Europe with protests as far afield as Moscow and Madrid.
Demonstrations against the killing were seen in cities across the continent with left-wing radicals and other sympathisers taking to the streets.
In Spain, 11 protesters were arrested and several police officers injured when clashes took place in Madrid and Barcelona.
In Copenhagen, 32 people were arrested when their protest in support of the Greek protests turned violent.
In neighbouring Turkey, about a dozen left-wing protesters daubed red paint over the front of the Greek consulate in Istanbul.
