The International Union of Muslim Scholars (IUMS) on Tuesday criticized the reported arrest of Muslim preachers and scholars in Saudi Arabia.
Those said to have been detained included Salman al-Auda, a prominent Muslim preacher and member of the IUMS's board of trustees.
On Monday, activists reported on social media that the Saudi authorities had detained more than 20 Muslim preachers and scholars for unspecified reasons.
Alongside Auda, those reportedly detained include prominent Saudi preachers Aaidh al-Qarni and Ali al-Omari.
On Sunday, Khalid bin Fahd al-Auda tweeted that the Saudi authorities had arrested his brother Salman. He did not say when the arrest took place or speculate about the reasons for the move.
Saudi Arabia is yet to issue any official statement regarding the reported arrests.
In a statement issued late Monday, the Doha-based IUMS suggested the arrests were related to an ongoing diplomatic crisis -- now in its fourth month -- pitting Qatar against a four-nation Arab bloc led by Saudi Arabia.
