Saudi Arabia Sets Blackberry Messenger Block Deadline [bbc.co.uk]
Saudi Arabia's telecoms watchdog has called on telecoms firms in the country to block the messenger function on Blackberry handsets from Friday.
The watchdog said the ban would last until the state's three mobile phone operators "fulfil the regulatory requirements it has requested".
But the Communications and Information Technology Commission (CITC) did not reveal what these requirements were.
The United Arab Emirates threatened on Sunday to ban some Blackberry services.
