RIYADH: Saudi authorities have ordered shops employing both men and women to build separation walls to enforce the strict segregation laws of the ultra-conservative kingdom, local press reported Monday.

The order that was issued by labour minister Adel Faqih also had the stamp of Abdullatif al-Sheikh, the head of the Commission for the Promotion of Virtue and Prevention of Vice, commonly known as Mutawa and religious police, several dailies reported.

It stipulated that a separation barrier, not shorter than 1.6 metres (over five feet), should be erected to divide working men and women.

Authorities in June 2011 told lingerie shops to replace their salesmen, mostly Asian, with Saudi saleswomen. This directive was later extended to cosmetic outlets.

Saudi women have long complained they feel uncomfortable having to buy lingerie from men and would prefer female sales assistants.

In December, the head of the religious police strongly criticised the labour ministry, claiming that saleswomen do not have a proper working environment and that some have been harassed.

The labour ministry had said the decision to employ women at lingerie shops should create some 44,000 jobs for Saudi women, among whom unemployment is more than 30 percent, according to official figures.
