The Israeli military and Shin Bet said a strike in the Gaza Strip killed Zaki Youssef Mahmoud Abu Mustafa, whom they described as a Palestinian Islamic Jihad commander involved in the October 7, 2023 abduction of Yagil Yaakov from Kibbutz Nir Oz.
The agencies announced the operation on Sunday and said the strike took place on Friday. They identified Abu Mustafa as a Nukhba commander in Islamic Jihad’s Khan Yunis Brigade. The supplied reports did not contain confirmation from Islamic Jihad or an independent account of his death and alleged activities.
Yaakov was 12 when he was abducted. He was released from captivity in November 2023 during the first group of hostage releases, according to the evidence. The Israeli agencies presented Abu Mustafa’s alleged role in that kidnapping as one basis for the strike.
They also accused him of playing an important part in attempts to rebuild Islamic Jihad’s operational capabilities and of advancing attacks against Israeli troops in Gaza. The agencies further alleged that he exploited Nasser Hospital in Khan Yunis by trying to train fighters at the facility. The supplied accounts gave no independent substantiation for that hospital-related allegation and did not describe the claimed activity in greater detail.
The IDF said precision weapons were used and that advance measures were taken to limit danger to nearby civilians. No outside evaluation of those precautions was included, and the reports did not state whether anyone else was killed or injured in the strike.
A separate Israeli strike killed Mohammed Osama Abd al-Aziz Saba al-Eish, whom the IDF identified as a Hamas Nukhba member. The military alleged that al-Eish recruited and helped train new Hamas members. That operation was mentioned in the same announcement but was distinct from the strike on Abu Mustafa.
The central details in both supplied publications trace back to the joint IDF and Shin Bet statement. Their agreement therefore reflects a common official source rather than two independent investigations. This distinction matters because the affiliation, rank, conduct and use of the hospital were all claims made by parties to the conflict.
On the evidence available as of June 21, Israeli authorities had announced Abu Mustafa’s death and set out their reasons for targeting him. The material supports reporting the announcement and the agencies’ identification of the target, while leaving the underlying allegations explicitly attributed. No response from Palestinian Islamic Jihad, hospital officials or other witnesses was supplied. The announcement supplied no operational evidence beyond the agencies’ account.
