Jerusalem’s Pride parade, which takes place this afternoon, will have unprecedented security after a 16 year-old was stabbed to death by an Orthodox man at last year’s event.

Some 2,000 police are expected to supervise the march following the attack by Yishai Schlissel last year in which 6 people were stabbed and one, a 16 year-old girl named Shira Banki, was fatally injured.

Banki’s parents have called on the public to attend the parade, which this year is in memory of Shira, in a show of force against the violence that killed their daughter, reports The Times of Israel.

Schlissel’s brother, Michael, was detained by police yesterday following intelligence reports that suggested he planned a follow-up attack on this year’s parade.

A second man was also arrested yesterday on suspicion of planning to attack parade-goers. Four women were also arrested for spray-painting supportive graffiti along the parade route.

Last month, Jerusalem’s mayor Nir Barkat caused controversy after stating he wouldn’t march in the this year’s parade out of respect for the city’s religious community, which he said was offended by the display of gay pride.

Security officers, 2,000 of whom will patrol this year’s parade, were widely criticised on social media when it was revealed that they were given intelligence reports and profiles of suspect individuals – including Schlissel – who could interfere with the parade.

Schlissel, an ultra-Orthodox Jew, had been released two weeks before the attack after serving 12 years in prison for a similar assault on gay Pride marchers in 2005.

This year’s parade is expected to attract around 5,000 participants.
