Three ready-to-use improvised explosive devices (IED), each weighing between three to 20 kgs, were recovered from a terrorist hideout in the border district of Poonch on Wednesday, officials said.  They termed it a “major breakthrough” ahead of Lok Sabha elections in Jammu and Kashmir. The IEDs, planted inside steel containers of five-kg, 10-kg and 20-kg capacity, were found hidden inside a cave hideout during a joint search operation by the police, CRPF and Rashtriya Rifles in the forest area of Sanai-Gursai in the Mendhar sub-division, the officials said.
