(reuters) -- Zeid Ra'ad al-Hussein, in a speech opening a three-week session of the U.N. Human Rights Council, said that the Palestinian people were marking "a half-century of deep suffering under an occupation imposed by military force".
Israelis also "deserve freedom from violence", he said, adding: "Maintain the occupation and for both peoples there will only be a prolongation of immense pain."
U.N. staff reported on Monday that 163 Iraqi civilians were shot and killed by ISIS in western Mosul on June 1 "to prevent them from fleeing," Zeid told the Geneva forum, which U.S. ambassador Nikki Haley will address later in the day.
