Israeli police say a man has stabbed several people at a gay pride parade in central Jerusalem.

Spokeswoman Luba Samri says the attack took place Thursday evening. Eli Bin of Israel's emergency service said six young people were wounded, two of them seriously.

Witnesses told Channel 2 TV that an Ultra-Orthodox Jewish man rushed the marchers and stabbed multiple people before Israeli police jumped on him and arrested him.

Yishai Avior told the station that he heard screaming and saw three people on the ground bleeding.

A similar attack took place at the event in 2005.

Jerusalem's annual parade is smaller and more restrained than the annual gay pride march in Tel Aviv, which was attended by some 100,000 revelers last month.
