On Monday, the army said "many rioters" tried to breach the border fence and "approximately 10 explosive devices and several firebombs were used to target the security fence and (Israeli) troops".
Israel regards all of Jerusalem, including the eastern sector it captured in the 1967 Middle East war and annexed in a move that is not recognized internationally, as its "eternal and indivisible capital".
