Srinagar, Dec 30 : Taking a stern action in the wake of zero per cent results in tenth class board examinations, Jammu and Kashmir's Indian Administrated Chief Minister Omar Abdullah has ordered suspension of 21 principals, including nine in the summer capital, Srinagar, for their dismal performance.

The Education Department has also been advised to issue show cause notices to all such private schools which also registered zero per cent results so that appropriate action can be taken against such schools accordingly as well.
