I think I heard someone say that allows them to order schools closed, etc.
I would think that some of the Israeli authorities are irked that some of the citizens are not staying in their safe rooms when they should. The video has been showing a few residents coming out to gawk at damage after the missile hits. If any get tipped with chemicals, that would be a very bad idea. The locals need to stay indoors when the authorities say so.
Remember, a Hamas faction in Gaza claimed to fire the first chemical tipped Qassam into the Negev a week or two ago (right before this all got escalated with the Hezbollah kidnapping)
