The crush occurred as tens of thousands of ultra-Orthodox Jews thronged to the Galilee tomb of 2nd-century sage Rabbi Shim Bar Yochai for annual Lag B'Omer commemorations that include all-night prayer, mystical songs and dance.

Witnesses said people were asphyxiated or trampled in a tightly packed passageway, some going unnoticed until the PA system sounded an appeal to disperse, as crowds packed the Mount Meron slope in defiance of COVID-19 warnings.

Medics said 103 people had been injured in what they described as a stampede. Casualties included children, witnesses said.
