Participants at Gay Pride Jerusalem stabbed
At the Gay Pride march in Jerusalem six participants have been stabbed. Two of them are seriously injured, Israeli emergency services say.
On pictures one can see that the alleged offender, an ultra-orthodox Jew, is arrested. He is the man who ten years ago at the Gay Pride in the Israeli capital conducted a similar attack. Then, four people were injured. The man was convicted to twelve years in prison and was released three weeks ago.
“We heard people screaming, everyone tried to get themselves to safety. Bloodied people lying on the ground,” says a witness.
Despite the stabbing, the march continued. “Our struggle for equality will only get stronger because of this,” said the organization.

Jerusalem Mayor Nir Barkat acknowledged Thursday that “something went wrong” in the failure of police to monitor Schlissel, who while in prison had repeatedly used ultra-Orthodox social media to promote attacks on gays and describe his knifing spree as a “mission from God”. … “The writing was on the wall,” commented Israel’s Channel 2 reporter Moshe Nussbaum. “Everybody knew, except the police…about Schlissel’s intentions”: here.
