Israeli troops on Saturday killed an Arab man carrying a firebomb after he cut through a border fence from Jordan, the army announced.

It was the eighth attempted infiltration from Jordan this year.Arab reports said witnesses saw a second man wounded and captured him, but an army spokesman denied this.

"An army border patrol spotted tracks of one individual," said the spokesman, who cannot be identified by name under military regulations. "They followed them until they encountered the person and opened fire."

The incident occurred near the Jewish settlement of Argaman in the occupied West Bank. Argaman is 30 miles northeast of Jerusalem.

The dead infiltrator was carrying a firebomb and two copies of the Koran, the Moslem holy book, the spokesman said, suggesting he was a Moslem fundamentalist.

In the last reported infiltration from Jordan, an Israeli soldier was killed Nov. 13 by a 17-year-old Jordanian who penetrated an army position near the Adam Bridge near the West Bank city of Jericho. The teenager was captured.

Also Saturday, the body of a retired Palestinian postal worker was found in the West Bank town of Jenin, Arab hospital officials said.

They identified the man as Yasser Abul el-Assan, 35. Jenin residents said he was suspected of collaborating with Israeli authorities but that no Palestinian group immediately claimed responsibility for the attack.

The army confirmed the killing and said it was under police investigation.

El-Assan's death raised to 322 the number of Palestinians suspected to have been killed by fellow Arabs since Palestinians launched an uprising against Israeli rule three years ago. Most were accused of collaboration with Israeli authorities.

At least 779 Arabs have been killed by Israeli soldiers or civilians, and 57 Israelis have also died in the violence.
