By Our Reporter armyWith the fate of the constitution becoming uncertain owing to the growing difference among the key political forces over the constitution amendment proposal,  Chief of the  Army Staff Rajendra Chettri  has asked the NA officials to face the challenges. COAS Chhetri made the comment recently hinting that the country is likely to face conflict due to the unrest in Tarai in case the Tarai-based parties launch another agitation. Indeed, most Nepalese people have a faith only on NA to protect the national unity, integrity and sovereignty. Meanwhile, Prime Minister Pushpa Kamal Dahal termed India and China visit of former King Gyanendra as a part of conspiracy hatched against republic set-up and federalism.
