An Egyptian court has remanded to custody the daughter and son-in-law of Yusuf al-Qaradawi, the chairman of the International Union of Muslim Scholars who is in exile in Qatar, a judicial source told Anadolu news agency on Monday.

Ola al-Qaradawi and husband, Hisham Halet, were set to be released after being detained for 15 days. Instead, their detention will continue.

They are accused of being “members of an illegal organisation” – referring to the Muslim Brotherhood, which is banned in Egypt  and for “planning terrorist action against the security of public institutions”.
