Israel wanted to shake up the situation by making Gaza Chief Yahya Sinwar and Deif nervous that if the IDF could get to Issa, he could also get to them.
The sources also said that UNRWA could be replaced with the World Food Program.
Born in the Khan Yunis refugee camp, Sinwar, 61, was made Hamas' leader in Gaza in 2017. Since Oct. 7, Israel has considered him and other leaders to be "living on borrowed time."
