Jammu and Kashmir's most wanted terrorist Zakir Musa, who's believed to be the chief of Al-Qaeda's Ansar Ghazwat-ul-Hind, has been killed in an encounter in Tral, police said. A joint team of Army's 42 RR, SOG and CRPF launched a cordon and search operation after receiving intelligence input about Musa's location. He'd been hiding there for a couple of days.
