At the CDDH, Egypt expressed “its disappointment at the failure of the Philippine amendment, establishing as a grave breach the use of prohibited weapons, to be adopted”, but noted that Article 74 of the draft Additional Protocol I (now Article 85) “as it stands now does cover the use of such weapons through their effects”.
