The Israeli army said on Friday that there are mounting indications that a strike in Gaza killed Hamas military chief Mohammed Deif a week ago.

"There are increasing signs that imply a successful elimination of (Mohammed) Deif," Israeli military spokesman Rear Admiral Daniel Hagari told a press conference. 

Israel has already announced the July 13 strike killed Rafa Salama, commander of Hamas's Khan Younis Brigade, adding the two Hamas leaders "were sitting next to each other at the time of the strike."

Israel has accused the two of being the "masterminds" of the October 7 Hamas attacks against Israel.

But a Hamas official, without providing proof, has said Deif, commander of the group's military wing, was "well and directly overseeing" operations despite the strike. 

"Hamas is concealing the fate of Deif, but we will find out and reveal what happened to him," Hagari said on Friday.

The airstrikes on Saturday in Khan Younis have killed at least 90 Palestinians, according to the Gaza-based health authorities.
