A special TADA court in Jammu on Tuesday adjourned the hearing in case involving Kashmiri separatists leader Yasin Malik currently under trial for the killing of four IAF personnel and kidnapping of Rubaiya Sayeed. The court fixed the next date of hearing on Oct 23. The Tihar Jail authorities, where Yasin Malik is lodged, on Tuesday expressed their inability to produce jailed Kashmiri separatist leader in the court which allowed trial via teleconferencing.
