These craters used to be Fadjr-5 long rage artillery rockets set in underground launchers, hidden amongst civilian population.
I can’t emphasize enough the great lengths Israel is going through to not hurt civilians, while destroying these artillery rockets that Hamas purposely hid amongst civilian population.
