Six people have been wounded in a stabbing incident at a gay pride parade in Jerusalem, Israel.

BBC reports the suspect Yishai Schlissel, an ultra-Orthodox Jew, was released from prison just three weeks ago after serving a sentence for stabbing four people at the same parade in 2005.

Two are believed to be in a serious condition, according to the ambulance service.

The event has seen tensions between secularists and a number of orthodox communities, and a heavy police presence is spread across the parade route.
