CANBERRA, Australia -- A group believed to be planning a terrorist attack in the Indonesian city of Surabaya is associated with Jemaah Islamiyah, the al-Qaida-linked organization blamed for the Bali bombings, Australia's foreign minister said Sunday.

Foreign Minister Alexander Downer spoke a day after the ministry warned Australians not to travel to Surabaya.

He said intelligence sources are not sure Westerners are the planned target but noted the group "has denounced foreigners and clearly been at least inclined to mount terrorist attacks against foreigners."

The government has warned Australians not to travel to Indonesia since Oct. 12, when bombings on the island of Bali killed more than 200 people.

, including 89 Australians.

Surabaya, on Indonesia's main island of Java, has been the scene of street protests over U.S.-led military attacks in Iraq. Australia has contributed 2,000 troops to the war in Iraq.
