• NIA custody of three doctors and a preacher extended by four days in the Red Fort blast case.
• The accused, including Dr Muzammil Ganai, Dr Adeel Rather, Dr Shaheena Saeed, and Maulvi Irfan Ahmed Wagay, were produced after their initial 10-day custody expired.
• The November 10 Red Fort blast involved an explosives-laden car driven by Dr Umar-un-Nabi, killing 15 people.
