I'm Unconvinced

Somehow, I don't find the Human Rights Watch report convincing:-

Human Rights Watch researchers have visited the site to examine the fatal crater and have interviewed victims, witnesses, security and medical staff.

“There has been much speculation about the cause of the beach killings, but the evidence we have gathered strongly suggests Israeli artillery fire was to blame,” said Sarah Leah Whitson, director of the Middle East and Africa division at Human Rights Watch. “It is crucial that an independent investigative team, with the necessary expertise, verify the facts in a transparent manner.”

Human Rights Watch researchers currently in Gaza interviewed victims, witnesses, Palestinian security officers and doctors who treated the wounded after the incident. They also visited the site of the explosion, where they found a large piece of unoxidized jagged shrapnel, stamped “155mm,” which would be consistent with an artillery shell fired by the IDF’s M-109 Self-Propelled Artillery.

Human Rights Watch spoke to the Palestinian explosive ordnance disposal unit who investigated three craters on the beach, including the one where the civilians were killed. According to General Salah Abu `Azzo, head of the Palestinian unit, they also gathered and removed shrapnel fragments consistent with 155mm artillery shells.

Eyewitnesses interviewed by Human Rights Watch described between five and six explosions on the beach between 4:30 p.m. to 5 p.m., the time frame when the IDF fired artillery onto the beach and when the seven civilians were killed. Two survivors said they heard the sound of an incoming projectile and saw a blur of motion in the sky before the explosion that killed the seven civilians. Residents of northern Gaza are familiar with the sounds of regular artillery fire.

Doctors also confirmed to Human Rights Watch researchers that the injuries from the attack, which were primarily to the head and torso, are consistent with the heavy shrapnel of artillery shells used by the IDF. Doctors said the shrapnel they removed from Palestinian patients in Gaza was of a type that comes from an artillery shell.

According to readings from a Global Positioning Satellite taken by Human Rights Watch, the crater where the victims were killed was within the vicinity of the other artillery craters created by the IDF’s June 9 artillery attack and was the same shape and size. One crater was 100 meters away from the fatal crater, and the rest were 250 to 300 meters away.

However, according to on-site investigations by Human Rights Watch, the size of the craters and the type of injuries to the victims are not consistent with the theory that a mine caused the explosion. The craters are too large to be made by bounding mines, the only type of landmines capable of producing head and torso injuries of the type suffered by the victims on June 9. Additionally, Palestinian armed groups are not known to have, or to have used, bounding mines; the Palestinian government bomb squad said it has never uncovered a bounding mine in any explosive incident.
