'Second cell poised for Indonesia attack'

"There is intelligence suggesting that there is a second group active in the area," Australian Federal Police Commissioner Mick Keelty told ABC radio.

"Intelligence comes through all the time about threats and possible threats and there's further intelligence in the last 24 to 48 hours of a second group," said Keelty, who flew to Jakarta to investigate the blast.

Indonesian police have launched a nationwide hunt for al-Qaeda-linked Jemaah Islamiah militants blamed for the suicide car bomb attack that killed nine Indonesians and injured 182 outside the Australian embassy on Thursday.

Indonesian news portal Kom-pas.com reported that police had narrowed their search for two Malaysians, Azahari Husin and Noordin Mohamed Top, to densely populated central and eastern areas of Java, Indonesia's main island.

Azahari is a bomb-making expert and member of the al-Qaeda-linked Jemaah Islamiah.

Indonesia police have also released a videotape of the explosion taken from a security camera which shows a small box-shaped van exploding in front of the embassy on one of Jakarta's busiest streets.

Keelty's warning came as Australian government ministers broke off campaigning for the Oct. 9 election to gather in Sydney for a cabinet security committee meeting. Opposition Labor leaders also met to discuss security issues.
