Tests for a countrywide network aimed at substituting services run through the world wide web have been carried out by Iran's ministry of information and communication technology, according to a newspaper report. The move has prompted fears among its online community that Iran intends to withdraw from the global internet.

The police this week imposed tighter regulations on internet cafes. Cafe owners have been given a two-week ultimatum to adopt rules requiring them to check the identity cards of their customers before providing services.

"Internet cafes are required to write down the forename, surname, name of the father, national identification number, postcode and telephone number of each customer," said an Iranian police statement, according to the news website Tabnak.

"Besides the personal information, they must maintain other information of the customer such as the date and the time of using the internet and the I.P. address, and the addresses of the websites visited. They should keep these informations for each individual for at least six months."
