The male tourists, all aged 19 or 20, were at Banteay Kdei, near the temple complex that includes Angkor Wat in the western province of Siem Reap, when they were apprehended on Thursday (January 29), the Cambodia Daily reported.
They were tried over the weekend and fined 1 million riel (B7,500) each, given six-month suspended sentences and deported, the report said.
"We won't allow them to enter Cambodia for four years and confiscated their [camera] equipment," said Chau Sun Kerya, spokeswoman for the cultural authorities, according to the newspaper.
