Police 
            in Jakarta have uncovered the chassis number of the van thought to 
            have been used in last Thursday's bomb attack outside the Australian 
            embassy. 
            Similar information proved vital in the hunt for those behind the 
            Bali bombings in October 2002. 
            
Police have also found traces of chemicals used the bomb at a 
            house near Jakarta. 
            
At least nine people were killed in Thursday's explosion, and 
            more than 180 were wounded. 
            
"The chassis number of the vehicle used in the bombing has been 
            discovered," Australian Federal Police Commissioner Mick Keelty said 
            on Monday. 
            
"People might recall that that was one of the early leads in the 
            Bali bombing that led to the identification of those responsible," 
            Mr Keelty said. 
            
There is mounting speculation that the militant network behind 
            the Bali attack - Jemaah Islamiah - also carried out the Australian 
            embassy bombing. 
            
Chemicals found 
            
Investigations into the blast continued on Monday, with 
            Australian forensic experts helping Indonesian police in their 
            search for clues. 
            
Indonesian police chief General Da'i Bachtiar confirmed that 
            investigators had discovered traces of TNT and sulphur nitrate - 
            chemicals used in the embassy bomb - at a house near Jakarta. 
            
Police say they believe the bomb, made from around 200kg of 
            explosives, was packed into the back of a white minivan and 
            detonated as close as possible to the target.

Indonesian 
            police say they have also found suicide notes from men suspected of 
            taking part in the attack. 
            "We have found letters for their parents which said that they 
            were going to carry it (the suicide bombing) out," Mr Bachtiar told 
            reporters. 
            
Investigators are trying to determine whether the remains of two 
            unidentified bodies at the scene of the explosion are those of the 
            suicide bombers. 
            
DNA samples taken from the remains have been sent to Australia 
            for further analysis. 
            
The authorities in Malaysia are also helping in the hunt for the 
            perpetrators of the bomb attack. 
            
Indonesian police have named a fugitive Malaysian bomb-making 
            expert, Dr Azahari Husin, as a suspect, along with another Malaysian 
            JI member, Noordin Mohamad Top. 
            
Malaysian Defence Minister Najib Razak told Reuters new agency 
            that he would not be surprised if Islamic radicals already on 
            Malaysia's most-wanted list were involved in Thursday's attack. 
            
            
Increased security 
            
Officials based in western embassies are continuing to warn of 
            the possibility of another attack. 
            
People are being advised to avoid large apartment complexes, 
            particular those in the same district as the Australian mission. 
            
Australian Prime Minister John Howard said over the weekend that 
            he would increase security at Australia's diplomatic missions around 
            the world in the wake of Thursday's attack. 
            
The Australian embassy in Jakarta and its consulate in Bali will 
            be relocated, and bomb-proof windows will be installed in other 
            Australian embassies, Mr Howard said. 
            
Mr Howard faces criticism in Australia, after both he and Foreign 
            Minister Alexander Downer said last week that an SMS message warning 
            of the attack had been sent to Indonesian police 45 minutes prior to 
            the blast. 
            
The Indonesian police rejected the claim, and Australian 
            officials now concede that the SMS warning may never have existed.
