Nusa Dua, Bali – Indonesia on Monday called for greater vigilance and cooperation in the fight against terror, as counter-terrorism chiefs from around the world met in Bali.

Security Affairs Minister Djoko Suyanto told delegates from 22 countries that Indonesia had struck a significant blow against Southeast Asian terror networks in recent years but there was no room for complacency.

"Although a number of terrorists have been killed, captured and punished, some by way of execution, the entire terrorist network has not been uncovered," he said at the start of the International Seminar on Counter-Terrorism, organized by Indonesia's new National Anti-Terror Agency (BNPT).

"The terror groups are still actively recruiting, training and making efforts to carry out attacks."

Militants with links to global networks including Al-Qaeda have struck mainly Muslim Indonesia repeatedly since 2000, notably the 2002 bombings on the resort island of Bali, which killed 202 people, mostly Western tourists.

Senior counter-terrorism chiefs from Australia, France, Germany, India, Japan, Pakistan and the United States among others are attending the three-day meeting, according to Indonesian officials. They are expected to discuss ways to improve cooperation and coordination of counter-terrorism efforts across international borders.

"Terrorism is not a problem of one country but an international problem which requires synergy and cooperation between various countries. No country can deal with it alone," Indonesian foreign ministry security official Febrian Ruddyard said.

BNPT director Ansyaad Mbai said countries had to be more "proactive" in combating extremist ideologies that lead to terrorism. "We can't be reactive and wait for bombings and armed attacks to take place. We must be more proactive. The best prevention is through neutralizing the radical ideologies that trigger terror acts," he said.

Scores of suspected militants have been killed or captured in Indonesia since the last major attack – twin suicide blasts on US-owned luxury hotels in central Jakarta that killed seven people last year. Three men convicted of organizing the 2002 Bali bombings were executed by firing squad in 2008.

Another Indonesian militant, Hambali, is in Guantanamo Bay for allegedly plotting the Bali suicide bombings on behalf of regional terror network Jemaah Islamiyah.
