Palestinians across the West Bank and Gaza marked Nakba anniversary on Monday.
Nakba, which means catastrophe, refers to the creation of the state of Israel in 1948.
Hundreds of thousands of Palestinians fled or were forced from their homes and they and their families still live in UN run refugee camps throughout the region.
Their desire to return to their ancestral homes is one of the most intractable issues of the Arab Israeli conflict.
Israel says it will never accept a “right of return,” arguing it would threaten the state by diluting its Jewish majority.
In the West Bank city of Bethlehem as well as near Ramallah, hundreds of youths clashed with Israeli security forces.
Israeli troops fired tear gas, rubber bullets and water cannon to disperse them.
