Investigating judge at the Phnom Penh Municipal Court, Ky Rithy, summoned eight more witnesses in the trial of jailed opposition leader Kem Sokha, who stands accused of treason. Among them are NGO heads, and former CNRP activists; some of them have fled the country.
Summons were issued for: Sia Phearum, executive director of the Housing Rights Task Force; Chak Sopheap, executive director of the Cambodian Center for Human Rights; and Pa Nguon Teang, executive director of the Cambodian Centre for Independent Media.
Also summoned to testify are: Khoeun Viurath, Keo Rothna, Meas Kimseang, Heng Piseth and Kry Song.
These five are ordered to appear in court on the last week of May.
The NGO executives are scheduled to appear in June: Ms Sopheap on the 7th, Mr Nguon Teang on the 9th, and Mr Phearum on the 12th.
Kem Sokha is accused of colluding with the United States to topple the government via a colour revolution. He was arrested in September last after incriminating video footage (him saying the US government had been helping him push for regime change in Cambodia since 1993) appeared on Facebook.
