A criminal investigation is still ongoing in order to identify the source of the mysterious, chlorine-like smell that overtook the Gush Dan area on Thursday, according to the Environmental Protection Ministry. The ministry said it would continue to conduct tests and update the public as to the results.

On Monday morning, Ramat HaSharon residents complained of a second smelly situation - entirely unrelated to the Thursday incident. This stench was due to a gas pipe replacement on Sokolov Street, and quickly dissipated, the ministry reported.
