NEW DELHI: Last Independence Day, PM Narendra Modi took his security detail unawares when he broke the cordon to meet children on his way out of Red Fort. This did not go unnoticed by Islamic extremist groups who have been planning to target Modi, according to well-placed sources. The special Protection Group (SPG) that protects the PM is in a tizzy over an intelligence alert that terrorist groups, including Islamic State adherents, could be preparing teens to carry out a fidayeen attack on the PM. The inputs are understood to have said that boys aged 12-15 and trained in weapons and explosives may have sneaked into the country, triggering a high level of preparedness. The alert was issued on Friday and circulated among SPG, police and intel units in NCR.
