evidence: For the first time, India is constructing "permanent vertical bunkers" of concrete to station BSF troops right at the strategically significant Sir Creek and 'Harami Nalla' marshy area along the India-Pakistan International Border in Gujarat, official sources said. [...] While three pylon-shaped towers are coming up in the Sir Creek area, a 4,050 sq km marshy area between India and Pakistan, five such concrete structures will be constructed by the Central Public Works Department (CPWD) along the 'harami nalla' area spread across 900 sq km, sources said. [...] Sir Creek is a 98-km disputed territory between India and Pakistan in the Rann of Kutch marshlands, which opens up into the Arabian Sea. It divides the Kutch region of Gujarat and the Sindh province of Pakistan. The two countries have been holding talks to resolve issues related to the border dispute here.
