Prime Minister Narendra Modi on Friday held a meeting with Union Home Minister Amit Shah, National Security Adviser Ajit Doval and others after a probe indicated that a group of terrorists, killed in Jammu and Kashmir a day before, were planning "something big" ahead of local elections in the union territory. "Our security forces have once again displayed utmost bravery and professionalism. Thanks to their alertness, they have defeated a nefarious plot to target grassroots level democratic exercises in Jammu and Kashmir," PM Modi tweeted.
