From the Telegraph….

Greece has issued an international appeal for more tear gas after supplies ran low because police fired so much of it during a week of violent protests across the country.

Officers released 4,600 capsules of tear gas during confrontations in Athens and nearly a dozen other cities since riots erupted over the fatal shooting of a 15-year-old schoolboy by a policeman last Saturday.

The Greek government is urgently seeking fresh supplies of tear gas from Israel and Germany, the police said.
