İsrail´in, İran´ın nükleer tesislerini vurabileceği yönünde her gün yeni haberler gelirken, Hamas ilginç bir çıkış yaptı.

My attempt: "While every day there are coming news that Israel may shoot Iran´s nuclear facilities, Iran made an interesting exit (?)"

I don´t get the last part :/ What´s the idiomatic meaning of çıkış yapmak in this context?

çıkış yapmak means to show a reaction

Thanks

Btw, why isn´t there any dictionary which mentions that meaning? ;//

It seems to be an important one...

 tureng is a useful dictionary, but often you get too many meanings

I had checked out Tureng before, but I can´t see the one about "showing reaction" there.
