Prince Abdul Aziz, two prominent clerics among 20 arrested in Saudi Arabia

Among the those arrested is social media star and successful social entrepreneur Essam al Zamel

It related to a report that Qatar's Emir Tamim bin Hamad al-Thani and Saudi Crown Prince Mohammed bin Salman had spoken over telephone, an important step after four months of crisis between the two countries.

Following his five-year prison term, the cleric re-emerged as a supporter of the Saudi royal family.

Sheikh Ouda who was imprisoned from 1994-99 for agitating for political change and has 14 million followers on twitter, appears to have been detained over the weekend, Aljazeera suggested.

Hopes for a breakthrough were quickly dashed when Saudi Arabia suspended any dialogue with Qatar, accusing it of "distorting facts".

Saudi Arabia, Egypt, Bahrain and the United Arab Emirates cut ties with Qatar in June over its close ties to Iran and its alleged support for extremists.

"In regards to the crisis [with] the Gulf Cooperation Council (GCC) member states, al-Auda has done nothing but call for unity between these brotherly countries", the statement read, noting that his last tweet urged GCC members to "come together for the sake of their people".

Aljazeera, quoting social media postings reports that a prominent Saudi religious leader Sheikh Salman al Ouda (differently spelled due to different dialect in Qatar) has been arrested.

Some of the Sheikhs arrested have 10 to 15 million followers on Twitter, a lot of them Saudi youth.

A number of Saudi Arabian and Arab Muslim scholars have been seeking the release of their colleagues arrested on Sunday in the Kingdom, Quds Press has reported.

In the 1990s, the al-Saud battled the Muslim Brotherhood-inspired Sahwa [Awakening] movement that demanded political reforms.

A decade ago it fought off an al Qaeda campaign of attacks targeting officials and foreigners that killed hundreds. Further arrests took place on Monday, with Sheikh Ibrahim Al-Harithi, Sheikh Mohamed Al-Khodairi, Hassan Farhan, Gharm Al-Beeshi and others detained. Exiled Saudi opposition activists have called for protests on September 15 meant to galvanise opposition to the royal family.
