In a meeting with IDF investigator Major General Klifi on 19 June 2006, the IDF and Human Rights Watch agreed that it is possible that unexploded ordnance from a 155mm artillery shell fired earlier in the day could have caused the fatal injuries. According to the HRW report, the IDF fired more than 80 155mm shells in the area of the beach on the morning of the incident, and sand would increase the possibility of a fuse malfunction leading to a dud shell that may have sat in the sand waiting to be set off. The report says the shelling between 4:31 p.m. and 4:50 p.m. could have triggered a dud shell, as could the human traffic on the beach that afternoon.
