Four Israeli tourists intend to file a criminal complaint after being dragged out from a taxi and beaten by police in Bucharest, according to the Israeli Embassy in Romania.
The tourists were stopped on Friday evening in Victoria Square, where huge anti-government protests were being staged, while travelling to their hotel from a restaurant in Bucharest.
Between 30,000 and 50,000 people turned out for Friday's protest in the Romanian capital against the ruling Social Democratic Party.
The meeting descended into violence when gendarmes intervened and, according to demonstrators, used extreme force.
