NABLUS, June 3 (IslamOnline.net) - Israeli occupation forces are using a brand new chemically contaminated ammunitions to finish off Palestinian resistance fighters, a Palestinian doctor unveiled.

"The Israeli forces use chemical-contaminated ammo, which makes the skin of the victim fall once touched," Dr. Mohamed El-Hashim, of the Health Department in the West Bank town of Qalqiliya, told IslamOnline.net.

The Palestinian doctor cited Israeli-killed Mazen Yassin was the first case in point.

The 45-year-old leader of the Hamas military wing in Qalqiliya was shot by Israeli occupation forces while walking down one of the city's streets on May 20.

The Israeli soldiers fired one bullet at him, left him bleeding in the street and prevented civilians and ambulances from approaching him.

Two ours later, after using a Palestinian civilian to make sure he breathed his last, the Israeli soldiers removed the body, which was later handed to the International Committee of the Red Cross.

"A white-colored substance appeared on the lips of the deceased, an unprecedented thing I've never saw before," said Al-Hashim, who examined the body.

He said that Yassin was shot in the pelvis, an injury which he ruled could lead to his death, noting that he did not even loose much blood.

"He could not die simply because of being hit in the pelvis, a bony funnel-shaped cavity which causes no intensive bleeding," averred the doctor.

"I have been examining dead bodies since 1987, and I have never seen this before. The skin was falling out upon touching any part of the body."

"The odds is that he was hit by a bullet contaminated with a chemical material that gradually killed him or that he was injected by other poisonous substance the Israelis used for the first time." said Al-Hashim.

Eyewitnesses said Yassin fell on the ground upon being shot one bullet by the Israeli occupation soldiers, who denied access to him for full two hours.

"He was crying of pain. The soldiers forced me to approach and probe the body [for fear he was carrying explosives]," Saed Abdel-Hafez told IOL.

"He was injured in the pelvis. I told them he was dead. The soldiers then watched me making sure the body is not strapped with explosives."

Abdel-Hafiz said the soldiers then took the body on an army ambulance to the outside of the city.

Palestinians complain that Israeli forces even use police dogs or sharp tools to mutilate bodies of Palestinians.

On January 1, 2003, brothers Mohamed and Tarek Dawas, 14 and 15 respectively, were killed while trying to storm into Dugit settlement in northern Gaza Strip.

Medical sources said the bodies were riddled with knife cuts, and one brain was dashed out when the bodies were retrieved.

Israel has come under heavy fire for using internationally-prohibited weapons to kill Palestinians, and for using Palestinians to test drugs and poisonous medicines produced by its companies.

The Palestinian Information Center said in April that Israel used internationally-banned arms to crush the Palestinian Intifada, adding the "army resorts to deadly force to disperse the protestors with means only used in a showdown with other armies".
