Jerusalem on edge as violence flares at key holy site

Jerusalem (CNN) - Palestinians and Israeli forces clashed in and around the al-Aqsa mosque in Jerusalem's Old City for hours on Friday morning, before an uneasy calm returned to the city later in the day.

Videos shared on social media showed serious unrest and violence at the entrance to the mosque building from before sunrise with Palestinians throwing stones and firecrackers and Israeli security forces firing what appeared to be stun grenades and tear gas.

There were also early clashes at the Lions' Gate entrance to the Old City. 

By mid-morning, the Palestinian Red Crescent said more than 150 people had been taken to hospital with injuries from rubber bullets and stun grenades, as well as wounds sustained from beatings by police.
