Four people were killed Sunday when a crane collapsed at a construction site in Yavne.

Three men were crushed when the concrete slabs used to balance the crane came crashing down. A fourth man, who was trapped atop the crane, was also declared dead, despite efforts by rescue services and emergency medical response teams to save him.

The incident took place in the industrial zone of Yavne on Jabotinsky Boulevard.

A worker died of electrocution last month at the same site. Police said they are investigating the incident.

Last Thursday, one construction worker was killed in Petach Tikvah and another in Bnei Brak. According to the Workers’ Hotline organization, 38 construction workers were killed on the job in 2018. To date in 2019, 20 construction workers have died.

The Histadrut labor federation reached a deal last month enhancing safety regulations at building sites, including mandatory scaffolding and the regulation of cranes.
