The Economist:

As they struggled from the wreckage, poor Muslim congregations came to depend on foreign charities for help rebuilding their mosques, whose numbers have risen tenfold to around 250 today, says Bjorn Blengsi, an anthropologist. They also became receptive to imported versions of Islam, which tend to be stricter than the traditionally relaxed local variety. Agnès de Féo, another anthropologist and author of “L’Islam au Cambodge et au Vietnam” says both Wahhabism from Saudi Arabia and Tablighi Jemaat from India are gaining adherents.

Nothing wrong with that, perhaps. Most Islamic charities teach the faith and help the poor. But not, alas, all. In one much-publicised incident in 2002, according to the American government, a local member of the Kuwaiti-based Revival of Islamic Heritage Society (RIHS) helped an Indonesian fugitive, Riduan Isamuddin (alias Hambali), the mastermind behind the nightclub bombings in Bali. Hambali, who is now in prison in Guantánamo Bay, reportedly said he had hoped to bomb the American and British embassies in Phnom Penh and to use Cambodia as a base for terrorist operations throughout South-East Asia. RIHS, which has been cleared of links with terrorism by Kuwait’s government, remains active in Cambodia. A local affiliate, the Kuwait-Cambodia Islamic Cultural Training Centre, recently met the president of parliament.

The Khmer Rouge, I understood later, intended to eliminate the rich, the intellectuals, and anyone educated – like doctors, engineers and professors, the majority of whom tended to live in the city. For the Khmer Rouge these people were part of a dictatorial and corrupt regime that exploited the poor, and they sought to destroy everything they thought belonged to this world: buildings, luxury cars, villas, refrigerators.
…Everyone became quiet for a long time while wondering who would be the next victim. My heart was heavy with sorrow for the families of the deceased. Moreover, I had almost lost my daughters in the jungle during this same journey – a story too long to describe here.
With time, more and more of the new people died – from hunger, disease, from a plague of sheer exhaustion, but most of all from the massacres perpetrated by the Khmer Rouge. They killed people on perfectly ridiculous pretexts: wearing spectacles, knowing how to read or how to open the door of a car, even for having a white mark on the wrist (a sign of having worn a watch). For the Khmer Rouge, these were all signs that the person concerned belonged to a rich, dictatorial class.
It was common to see a man whose face was pale, trembling with fear, being paraded through the village with his hands bound behind the back, guarded on either side by Khmer Rouge cadre carrying large machetes. It was terrifying: everyone knew that they were going to decapitate this man. The scene served its purpose of warning us that the Khmer Rouge wielded absolute power. We lived from one day to the next. We had no idea what might happen to us in the night or on the following day.
