Three people suspected of negligence were arrested late Sunday afternoon in connection to the series of blasts that shook Ra’anana’s industrial zone earlier in the afternoon. Police said additional arrests are expected.

Sharon Region deputy police commander Ilan Mor ruled out arson and said the fire may have started with a welding accident setting light to gas canisters left on the premises. The fire was under control as of early evening Sunday.

Six people were lightly injured, Israel Radio reported. Authorities have confirmed that there were no people missing, as was initially feared.

The incident took place on Haharoshet Street, one of the main thoroughfares of the industrial and shopping area.

A large explosion, followed by subsequent smaller blasts, were all believed to be the result of a work accident that took place at a garage in the industrial area. Police were evacuating nearby businesses and stores as they feared additional explosions.
