IDF mistakenly killed 3 Israeli hostages in Gaza. This is what we know so far.

Alon Shamriz , Yotam Haim and Samer Talalka were taken by Hamas on Oct. 7 at the start of the war, along with more than 200 other hostages.

The three were “mistakenly” identified as a “threat,” an IDF spokesperson said on X at 1:17 p.m. ET on Friday .

The grave mistake has prompted an outpouring of anger and grief from Israelis .

Two of the killed hostages identified as Samer Fouad al-Talalka and Yotam Chaim Haim .

Alon Shamriz was 26 when he was killed and lived in the Young Generation neighborhood of Kibbutz Kfar Aza , the IDF says.

White House national security spokesperson John Kirby calls the incident “heartbreaking” and “tragic,” adding “obviously, this is not an outcome that anybody wanted to see”.

Samer Talalka's funeral was held in Hura on Saturday morning .

IDF chief of the general staff called Friday ’s incident a difficult and painful event’ Lt. Gen. Herzi Halevi said the shooting at the hostages was against the rules of engagement.

Halevi says he and the IDF are responsible for their deaths.
