Jerusalem police on Friday fired stun grenades to disperse scores of Arab youths who turned violent after being barred access to the Temple Mount for Friday prayers, police said. There were no injuries reported in the noontime clash near the Damascus Gate. Citing intelligence alerts over potential attacks, police prevented all Arab men under 40 from entering the Temple Mount due to the security situation in the country. Police sporadically close off the bitterly contested Jerusalem holy site to younger male Arabs on Fridays during times of high tension following multiple alerts over possible violence at the ancient compound.
