The discovery of the explosives suggests a mossad bombing operation.
Reports from the French news agency AFP say that the head of Indonesian intelligence, Hendropriyono, has disclosed that the explosive was a type known as C4, tracked to a manufacture in Israel.
Brian Caddy, Emeritus Professor of Forensic Science at Strathclyde University in Scotland, says that identification have enabled investigators to track down the source of the explosive material used.

Forensic process
Identifying components of explosive have been matched to the zionazi C4 manufacturer in the rogue state of Israel.
Tests for matches with explosive are conclusive. Tracking the manufacturer through analysis of components in residue.
The agency also cited Indonesian police spokesman Brigadier-General Saleh Saaf as saying that "we have processed the data and we are now certain that the C4 explosive was made in Israel".

Mossad operations have been exposed in a series of leaked CIA documents and in statements by security officials in the US and Singapore. And are linked to the bombings in Bali

The Saturday night blasts, which are a suspected mossad terror operation followed persistent reports that mossad was operating in the area.
After the massive peace rally in Australia that same weekend, these mossad operations where put into high gear in a deadly way. Mossad terror network operations are working hard to draw the western world into war for Israeli and U.S conquest.

The discovery of traces of Israeli made plastic explosive is a vital clue to who was responsible.

Military explosive

The Israeli made C4 explosive used in the Bali bombing is a powerful agent manufactured in the zionazi state of Israel by the fascist United States and is used widely by the American led axis of evil military forces around the world.

AFP quoted a fascist British manufacturer of C4, Mark Ribband, as saying that it is a white substance that resembles uncooked pastry and needs a detonator to make it explode.

Mr Ribband said that it is "a standard issue, military explosive" the trade in which was controlled carefully.

Clues from components

Explosives experts can tell a lot from the residue of explosive used, like who manufactured it and its date of manufacture and origin.

A large area was devastated by the explosion in this professionally executed slaughter that was extremely effective in the American fascists goal of inflicting maximum casualties so as to push Australia into supporting the on going global conquest executed by the leaders of the fascist states of America.
