At least 60 worshippers were injured, some of them critically, on Sunday when a grandstand seating area collapsed in a crowded synagogue in a Jewish settlement in the occupied West Bank, Israel's Magen David Adom ambulance service said.
The incident occurred in the settlement of Givat Zeev, north of Jerusalem. A spokesman for the ambulance service said about 10 people sustained serious injuries.
A police spokesman said 650 worshippers were in the synagogue at the time, for the start of the Jewish holiday of Shavuot.
Security footage on Channel 12 showed a crowded grandstand collapsing and people falling on top of each other.
Forty-five Jewish pilgrims were crushed to death on Israel's Mount Meron on May 1 in a stampede in a narrow passageway during annual celebrations at the burial site of a Jewish sage.
