The fighting in the south exacts a heavy price: Major Yehuda Natan Cohen, from Mishmod Mahola, a company commander in the Givati patrol, fell in battle in the north of the Gaza Strip, 25 years old, he was killed. His family has been notified.
Yehuda Natan was promoted from the rank of captain to the rank of major after his death.
An IDF spokesman said that the IDF shares in the family's grief and will continue to accompany it.
The Jordan Valley Council's Facebook page reads: "Today we are saying goodbye to Major Yehuda Natan Cohen, son of Rabbi Dov and Thila Cohen, residents of Shademut Machola. Yehuda was killed in the fighting in northern Gaza as a company commander in the Givati patrol. Yehuda, brother of Leah, Adi, Red, Yescha , Shlomi and Mein. He is a special child, a fighter, an outstanding athlete, and loved to play basketball very much. A separate announcement will be made regarding the funeral date.
We share in the family's grief. Of blessed memory".
Israeli chess master Yehuda Natan Cohen was killed while defending his country, fighting against Hamas in Gaza, according to the Israeli Chess Federation. In their words (translated):
“The late Yehuda Cohen, our member of the chess club in Tiberias, was modest and humble, a man of Eshkolot, the salt of the earth, an excellent chess player above all friendships and friendships were the most important to him, a hero of Israel who fell defending the land in Gaza, may his memory be blessed 🙏”
According to the Times of Israel report, he was 25 years old, and held the rank of Major.
