Israel’s military “failed in its mission” to rescue three hostages mistakenly killed by its troops in Gaza earlier this month, its chief of the general staff said today, as the military published the findings of its investigation.

According to CNN, the findings concluded that Israeli command ranks had information that hostages were present in the area, and “even took actions to prevent strikes on locations suspected of having hostages,” the report read.

But the investigation also concluded the Israeli forces in the field had “insufficient awareness” of the possibility that hostages would approach them or that the troops would encounter hostages in operations not specifically aimed at freeing them.
