Cambodia's UN-backed war crimes tribunal is set to issue its verdict in the trial of Kaing Guek Eav, the prison chief and the first senior member of the Khmer Rouge government to face justice in an international court.
Riot police lined up outside the court on the outskirts of the capital, Phnom Penh, on Monday as the court opened its session to hand down its verdict.
Kaing Guek Eav, better known as Duch, arrived at the court on Monday in a bullet-proof car and was whisked inside by security guards.
The verdict on charges of war crimes, crimes against humanity, torture and premeditated murder is scheduled to be broadcast live on all television and radio stations in Cambodia.
The verdict will be the first by the Khmer Rouge court, established in 2006 after nearly a decade of negotiations between the government and the UN.
Expecting the unexpected

Duch is the only senior Khmer Rouge figure to have acknowledged responsibility to the tribunal. Prosecutors asked for a 40-year sentence from the court, which cannot impose the death penalty.
Last year, Duch repeatedly used nine months of hearings at Cambodia's UN-backed court to beg forgiveness for overseeing the murders of around 14,000 people at the Tuol Sleng torture centre over three decades ago.
But the former math teacher, 67, one of five senior members of the communist movement detained by the court, then asked to be released on the final day of hearings on grounds that he was not a key leader in the government.
Few expect judges to take his acquittal demand seriously, although analysts speculate he will appeal his sentence after it was announced this month that he sacked Francois Roux, his French lawyer, for "lack of confidence".
"For Duch, the chamber will have to decide whether his apology was genuine, especially in light of his change of plea for acquittal at the end," Michelle Staggs, the deputy director at the Asian International Justice Initiative, said.
Duch will continue to be represented by Kar Savuth, his Cambodian lawyer, while the court itself has faced controversy during the trial.
Prosecutors spent most of the trial portraying Duch, who was captured in 1999, as a meticulous executioner who built up a huge archive of photos, confessions and other evidence documenting inmates' final terrible months.
The trial's format allowed Duch to comment on all testimony and repeatedly give his own version, painting himself as a terrified bureaucrat who performed his duty out of fear leaders would kill him and his family.

"I tried to survive on a daily basis, and that's what happened. And yes, you can say I am a cowardly person," Duch told the court in September.
The Khmer Rouge, led by "Brother Number One" Pol Pot, emptied Cambodia's cities during its 1975-1979 rule, exiling millions to vast collective farms in a bid to take society back to "Year Zero" and forge a Marxist utopia.
At least two million people were executed in the notorious "Killing Fields" or died from starvation and overwork before a Vietnamese-backed force toppled the government. Pol Pot died in 1998.
Other Khmer Rouge members awaiting trial next year are "Brother Number Two" Nuon Chea, former head of state Khieu Samphan, the ex-foreign minister Ieng Sary and his wife Ieng Thirith, who was the minister of social affairs.
