The Israeli Embassy in Bucharest protested to the Romanian government on Monday after four Israeli tourists were allegedly dragged out of a taxi and beaten by riot police during a violent anti-corruption protest in the Romanian capital on Friday.
The embassy described the attack on the Israelis as "unacceptable and extremely serious."
It said the four men were returning to their hotel in Bucharest when their taxi was stopped by police.
"They were dragged out of the car, even though they showed their passports and explained they had nothing to do with the protest," the embassy said, adding that the men would file a criminal complaint.
Police in Bucharest did not immediately respond to the statement.
However, Romanian President Klaus Iohannis on Monday called for a thorough investigation into police brutality during the anti-government prowwww.
"The brutal repression of demonstrators is totally unacceptable," Iohannis said. "In a European state, attacking innocent people, attacking journalists, attacking women and children, is inconceivable."
Some 500 people required medical treatment after police fired tear gas and water cannons to break up the protest, which was against government corruption. Some people lobbed rocks and bottles at police.
