EVEN as the nation observed Anti-Terrorism Day on May 21 to remind itself of Rajiv Gandhi's assassination five years ago, terrorists chose the day to remind the nation that they were alive, well and ticking. A bomb in south Delhi's busy Lajpat Nagar market killed 13 persons and injured scores of others. The identity of the killers is still not clear though it is believed to be the handiwork of the Jammu and Kashmir Islamic Front (JKIF). Its aim: to thwart the Lok Sabha election back home and prevent popular participation.
