Indonesia has drawn up plans for tougher anti-terrorism laws following last month's militant attack on the capital, including detention without trial for up to three months compared with a week now, government sources said Tuesday.

The proposals are likely to draw fire from human rights activists, who have warned against jeopardizing hard-won freedoms over nearly two decades since the end of authoritarian president Suharto's rule.

However, officials anticipate little opposition in parliament to the legislation, which would not be as strict as counter-terrorism laws passed in recent years by neighbors Australia and Malaysia.
