Terror attack possible in Indonesia

Australian travellers in Indonesia have been urged to exercise a high degree of caution after warnings that terrorists may be well advanced in plans for an attack.

That follows an attack on a Starbucks cafe in Jakarta on January 14, that resulted in the death of eight people including the four attackers.

The Department of Foreign Affairs and Trade smartraveller website said the alert also applied to the popular holiday destination Bali.

"We continue to receive information that indicates that terrorists may be planning attacks in Indonesia. An attack could occur anywhere at any time. Be particularly vigilant at places of worship and during significant holiday periods," DFAT said.

Indonesian police said people should be alert but not alarmed.

Indonesia's National Police spokesman Agus Rianto said warnings from Australia may be a result of increased chatter on social media and propaganda videos.

Local supporters of Islamic State have been circulating threats against police and national targets, such as embassies, government offices and airports, he said.

"This is a form of provocation and shows us we need to stay alert."

Australia's warning comes just days after DFAT issued an alert to its citizens living in Malaysia to be vigilant as terrorists may be planning attacks in Kuala Lumpur.
