JERUSALEM (AP) The Israeli military said Friday that it dismissed two officers and reprimanded three others for their roles in drone strikes in Gaza that killed seven aid workers on a food-delivery mission , saying they had mishandled critical information and violated the armys rules of engagement.

The findings of a retired generals investigation into the Monday killings marked an embarrassing admission by Israel, which faces growing accusations from key allies, including the U.S., of not doing enough to protect Gazas civilians from its war with Hamas.

The findings are likely to bolster widespread skepticism over the Israeli militarys decision-making. Palestinians, aid groups and human rights organizations have repeatedly accused Israeli forces of firing recklessly at civilians throughout the conflict a charge Israel denies.

Its a tragedy, the militarys spokesman, Rear Adm. Daniel Hagari, told reporters. Its a serious event that we are responsible for and it shouldnt have happened and we will make sure that it wont happen again.

With pressure mounting on Israel to hold itself accountable, Hagari and other officials late Thursday shared with reporters the results of the investigation.
