Seven aid workers were killed when their convoy was hit by an Israeli airstrike overnight, as it was leaving their Deir al-Balah warehouse, amid ongoing operations delivering aid supplies inside Gaza.

The food charity World Central Kitchen (WCK) said they had coordinated the convoy’s movements with the Israel Defense Forces.

In response to the strike, the IDF stated that it “is conducting a thorough review at the highest levels to understand the circumstances of this tragic incident.”

Israel’s Prime Minister Benjamin Netanyahu said on Tuesday the aid workers were killed in an “unintended strike.”

The destroyed vehicles bear the hallmarks of a precision strike, which only the IDF has the capability to conduct in the region.
