JAMMU: Border-related challenges had changed significantly over the past 60 years, and therefore advanced technological solutions must be adopted to effectively address them, Union home minister Amit Shah said Friday as he visited the Gurnam and Bobiyan outposts located along the India-Pakistan International Border in Kathua district of Jammu and Kashmir.Later in the evening, Shah chaired a high-level security review meeting in Jammu at Lok Bhavan, which was attended by LG Manoj Sinha, Army chief General Upendra Dwivedi, Union home secretary, IB director, J&K chief secretary and DGP, heads of CAPFs and other senior officers. At the meeting, while the home minister appreciated the efforts of the security agencies in dismantling the terror ecosystem, he directed them to remain alert and continue work in a coordinated mode to ensure that the gains made in recent times are sustained and the goal of a ‘terror free J&K’ is achieved at the earliest. He assured that all the resources would be made available by the govt to achieve this.Shah said the terror eco-system nurtured by elements inimical to the country in J&K had been almost crippled due to the concerted efforts of the Narendra Modi govt. Efforts for de-radicalisation had seen major success, he said, and instructed for taking more initiatives for youth engagement. Innovative measures to further reinforce the watertight security cordon were also discussed in the meeting. This was the second security review meeting chaired by the Union home minister within a month. On Jan 8, he had chaired a high-level review meeting in Delhi on J&K’s security situation.
