Why is Iran hitting civilian targets?

Tit for tat usually. Dimona strike in particular was:

"Commander of the IRGC's Aerospace Force, Brigadier General Seyyed Majid Mousavi, says that every ultimatum given to Iran is an act of war. Adds that the Iranian strikes on the strategic points in Dimona and Haifa in recent hours were in response to the US' 2 and 5 day threats."

As retribution for the attacks on their country I believe.

I dunno man. Why were civilian targets in Iran hit?

I guess you might feel justified to hit civilian infrastructure once your enemies are vile enough to hit yours.

Why are the US and Israel hitting civilian targets including at least one desalination plant?
