Bhopal/ Poonch, Jan 06 (ANI): Security expert said that Pakistan was trying to help militants enter India by firing at border posts in Jammu and Kashmir. Indian and Pakistani troops intensified cross-border firing overnight, even as one Indian border guard died in the firing. A senior Indian official with the border security force said they had retaliated against machine gun and mortar attacks on about 60 positions along a more than 200-km (125-mile) stretch of the border. A security expert, SR Sinho said that Pakistan was helping militants infiltrate in Indian Territory as they were planning something big before January 26. Amid the growing hostility, India's security agencies last week declared a nationwide alert to avoid militant strikes in the lead-up to visits by top US diplomat John Kerry and President Barack Obama later in January. Meanwhile, villagers living along the international border in Poonch district condemned the firing. A resident of Pakistan occupied Kashmir (PoK), Mohammad Iqbal said firing was not the solution.
