So it's been disclosed in the papers why the clashes between muslims and jews on Tisha B'Av started. Apparently a few days earlier a group of settler jews entered the Al Aqsa compound (where the Temple once stood) and were heckled muslim worshippers. Some took to filming the jewish group with their handphones. One settler woman looked into the camera and said that the muslim Prophet was a pig. This video went viral and muslims were up in arms since Saturday evening - the beginning of Tisha B'Av. http://www.timesofisrael.com/muhammad-insult-prompts-police-tisha-bav-alert-on-temple-mount/
Anyway scuffles continued throughout the morning yesterday in the streets of the Old City's Muslim Quarter.
