The 1997 Phnom Penh Grenade Attack

Under InvestigationSources: BLast updated: 14 October 2026

On 30 March 1997, four grenades were thrown into a peaceful crowd of about 200 people gathered in a park opposite the National Assembly in Phnom Penh, where opposition leader Sam Rainsy was leading a protest against judicial corruption. At least 16 people were killed and nearly 150 injured; among the dead was Rainsy's bodyguard, who shielded him. Rainsy escaped with minor injuries. A 1999 report prepared for the US Senate concluded that members of then Prime Minister Hun Sen's bodyguard unit took part in planning and carrying out the attack. No suspect was ever tried in Cambodia. In France, where Rainsy is a citizen, two former bodyguard commanders were tried in absentia in March 2025; the court postponed its verdict to examine new evidence.
