Ban finds "the apparent excessive use of force by Israeli security forces" to be "troubling," his spokesman Stephane Dujarric told reporters as violence continued in Jerusalem and the West Bank city of Bethlehem.
This "demands serious review as it only serves to exacerbates the situation leading to a vicious cycle of needless bloodshed," he said.
Prime Minister Benjamin Netanyahu said Tuesday Israel would use "all means" available to end Palestinian violence and that new security measures were planned.
A ministerial-level meeting of the Security Council on the crisis in the Middle East is scheduled for October 22.
After initially breaking out with attacks and violent protests in annexed east Jerusalem and the occupied West Bank, unrest has spread to Gaza, with clashes along the border in recent days leaving nine Palestinians dead from Israeli fire.
The violence began on October 1, when an alleged Hamas cell shot dead a Jewish settler couple in the West Bank in front of their children.
