Jerusalem, Apr 5 (UNI) The Israeli military on Friday admitted in a statement that its killing of seven workers with the World Central Kitchen (WCK) aid group was "a grave mistake stemming from a serious failure due to a mistaken identification and errors in decision-making." Israeli airstrikes targeted on Monday a convoy of the non-profit food charity in the Gaza Strip, resulting in the deaths of its seven workers from Australia, Canada/the United States (dual citizen), Gaza, Poland, and Britain.
