A Ukrainian man who was apparently attacked because he was identifiably Jewish has been flown to Israel for medical treatment.
Yeshivah student Aharon Alexander Gorshonov, was said to have been beaten up after he left the synagogue in Kiev on second night seder wearing a kippah.
The 25-year-old victim sustained head injuries and was discovered covered in blood later that night. According to the European Jewish Congress he was attacked in an area known to be popular with neo-Nazi groups.
Moshe Kantor, president of the EJC, urged the Ukrainian authorities to take swift action following the assault.
"We are confident that the Ukrainian authorities will act swiftly against the perpetrators of this hate crime and will bring them to swift justice." he said.
Mr Kantor said that the attack, coming weeks after the murders of four at a Jewish school in Toulouse, showed that European leaders needed to act now to stamp out "visceral hatred of Jews".
"We call on European leaders to act swiftly to strengthen legislation, bolster education and increase intelligence sharing to prevent what could become a tsunami of hate and violence against the Jews of Europe."
