skype whatsapp tangoSaudi Arabia’s Communications and Information Technology Commission (CITC) said it is placing messaging applications Skype, WhatsApp and Tango under review,  Arab News reported.

The CITC did not say whether the popular messaging applications would share the same fate as Viber, which has been suspended indefinitely. Sultan Al-Malik, CITC spokesperson said there will be an official statement regarding mobile applications that do not comply with current regulations.

He added that appropriate action will be taken against applications or services that do not comply with regulations.

On 5 June, the regulator suspended Viber for failing to comply with unspecified regulations. According to reports, the suspension was effected because monitoring is difficult for the state and it deprives licensed telecom companies of revenue from international calls.

Cyprus-based Viber was popular among Arab expatriates because it has an Arabic version and works on all operating systems and wireless networks. Earlier this year that Saudi Arabian operators STC, Mobily and Zain Saudi had been asked to tell the CITC if they were able to monitor or block such applications,  local media reported.
