Thousands of people gathered at Ramallah's Manara square waving Palestinian flags as well as black flags. Several protestors burned Israeli flags. Concerts are talking place in the square and Palestinian senior officials are scheduled to speak before the crowds.
Meanwhile, heavy security forces presence is felt in the West Bank. The forces are hoping to prevent spontaneous marches from reaching checkpoints.
An officer was lightly injured in Issawiya after protestors hurled stones at police and Border Guard forces. He was treated on site. Three suspects were arrested. Three Molotov cocktails were hurled at the back gate of the Hadassah Mount Scopus Hospital in Jerusalem. No injuries or damage were reported.
Hundreds of Palestinians also gathered at the Qalandiya checkpoint in northern Jerusalem and clashed with IDF soldiers. The IDF said that dozens of protestors were hurling stones. The army responded with crowd dispersal means. No injuries were reported.
