Indonesia is still under threat from terrorists despite the recent arrests of key insurgents, President Susilo Bambang Yudhoyono said Monday.
Yudhoyono said convicted terrorists tend to return to their old practices after completing their prison sentences.
"Although the key figures who had made our country insecure for the last 10 years have been disabled, terrorism remains a threat because the perpetrators who have been jailed still repeat the same acts," he said.
Police announced last week that they had foiled a plot to assassinate Yudhoyono, take over hotels, kill foreigners and establish an Islamic state.
Police have arrested 58 suspected terrorists and killed 13 in a series of raids since February, when authorities broke up a training camp run by a previously unknown group calling itself al-Qaida in Aceh.
