Warsaw - An Israeli attacked Gaza demonstrators who interrupted a ceremony that honored Poles who rescued Jews during World War II, Polish Radio reported on Thursday.

Members of the Anarchist Federation entered a lecture theatre Wednesday in Poznan and unfurled a banner saying, "Enough of the slaughter in Gaza" during a speech by Israel's ambassador.

A scuffle broke out when an Israeli citizen attacked the protesters, Polish Radio said.

The Israeli was taken to a hospital and three Poles were detained.

The award ceremony was given by the Yad Vashem Institute in Jerusalem, to posthumously honour two Poles who saved a Jewish girl from the Nazis. (dpa)
