Saudi Arabia has arrested prominent preacher and scholar Safar Al-Hawali just days after he published a book criticising the ruling family. Three of his sons – Abdul Rahman, Abdullah and Ibrahim – were also detained. Rights groups say Abdul Rahman and Abdullah were reportedly taken into custody while attending a family wedding on Wednesday. Hawali became known almost three decades ago as the leader of the Sahwa movement, which advocated for democracy in Saudi Arabia. Saudi Arabia, under Crown Prince Mohammed Bin Salman, has launched a crackdown against activists, religious figures and opponents in recent months.
