A huge blast caused by a gas leak killed four people in the coastal Israeli city of Netanya early on Friday, police said.

The explosion left 60 people injured and caused the first floor of a four-story residential building to collapse.

Local media had reported earlier that many people were trapped, but emergency services said everyone had been evacuated from the building.

Police spokesman Mickey Rosenfeld said investigators had ruled out sabotage and that the leak was most likely accidental, a Reuters report said.
