"Don't be dogs of Zionism - God will hold you to account," some demonstrators snarled at police in helmets who pushed them back from an Ankara stadium where Israel lost 0-3 to Serbia in a European Volleyball League women's match.

The game had been closed to the public because of security concerns.

With temperatures rising, Israeli supporters in the crowd outside folded the few Israeli flags that were on display and tucked them away.

Israeli security officials guarded the women volleyball players as they rode to the indoor stadium in a bus with tinted windows.

Protesters gathered two blocks from the stadium, some bearing posters with the image of 19-year-old Furkan Dogan - the youngest of the activists killed in the raid by Israeli naval commandos in the Gaza flotilla incident.

"Why kill and come here to play?" said protester Hanif Sinan, a landscape architect.

Some of the 100 protesters rapped police shields with the poles of their Palestinian flags and lobbed water bottles at security forces. Police tried their best to quell the trouble.

"Esteemed friends," appealed a police commander with a loudspeaker. "Please don't cause trouble."

Israeli team spokesman Yaron Michaeli said: "We know that the problem is only a political one. The players try to concentrate on what they have to do."

Hakan Albayrak, a columnist for Turkey's Yeni Safak newspaper who was a passenger on the ship Mavi Marmara during the raid, said: "We cannot harm any Israeli in our country, but we have the right to protest."

The government in Jerusalem last week lifted a travel advisory warning Israelis not to visit Turkey in the wake of the flotilla incident. However, Turkish hostility towards Israel has been mounting for some time.

In February - months before the flotilla incident - an Israeli basketball team playing in Turkey was pelted with glass bottles and forced to flee the court during a game.
