Indian Defence Minister Rajnath Singh is scheduled to visit the forward areas of Jammu and Kashmir starting June 16. The two-day visit to the Union Territory will include interaction with the troops. On June 17, he will attend the `Rajyabhishek` of the 200th anniversary of Maharaja Gulab Singh in Jammu. Earlier, Singh called for greater unity of civil administration and Armed Forces to further strengthen national security and deal with future challenges that may emanate from the ever-evolving global situation. He was addressing the participants of the 28th Joint Civil-Military Training Programme in Uttarakhand on Monday. The Minister pointed out that the concept of national security has broadened, as many non-military dimensions have been added to the more general aspect of protection from military attacks.
