On this day, SQ117 was hijacked by four Pakistani terrorists, who demanded the release of six key Pakistan People’s Party (PPP) activists from jail.

The successful resolution of the hijack was a multi-agency effort. ISD played a critical role in collecting tactical intelligence on the hijackers, which informed the government’s decision to storm the plane after the hijackers issued an ultimatum and threatened to kill the hostages. An ISD officer, who was part of the negotiation team, spoke to the hijackers in Urdu, causing them to rush to the cockpit. This diversion allowed the Singapore Armed Forces’ Special Operations Force to storm the plane.

Within minutes, the hijackers were neutralised. All crew and passengers were rescued.

The SQ117 hijack is a solemn reminder that Singapore may be indirectly but significantly impacted by foreign conflicts.

Come visit ISD at Booth A19! See you there! :)

24 years ago today, Singapore came dangerously close to a tragedy.

Unseen threats were stirring in our midst. The Jemaah Islamiyah terrorist network had plotted to conduct attacks across Singapore, including at Yishun MRT, Changi Airport and Sembawang Naval Base. Their objectives were, amongst others, to target American individuals and interests as part of their broader affiliation with the Al-Qaeda’s “global Jihad” ideology, and debilitate Singapore’s infrastructure and economy.

Had the JI succeeded, the peace and stability we often take for granted in Singapore would have been shattered.

Let’s never forget how close we came to such tragedy, and stay vigilant to protect our home.

ISD’s public education efforts are lesser known but some 200 youths got to hear how we work with the community to keep Singapore safe, at the annual ACG Youth Forum 2025 organised by the Singapore Muslim Women’s Association () and the Inter-Agency Aftercare Group (ACG). By understanding terrorism threats to Singapore and learning to spot signs of radicalisation, you can stay aware, protect your friends, family and community.
