It was a laser gun!

From that all-so-reputable Malaysian National News Agency:

Attallah Quiba, the Palestinian ambassador in Sri Lanka, believes that Palestinian leader Yasser Arafat was killed by unnamed Israelis using advanced technology, the Island newspaper said.

Responding to questions at a media conference in Colombo on Friday, Quiba claimed that two Israelis who met Arafat on the day he was taken sick “used a laser device to attack Arafat.”

“They tried to flee after using the device but were wrestled down by the Palestinian Authority security personnel. Both men were carrying Canadian passports.”
