A militant was caught alive following the attack on a BSF convoy on the Jammu-Srinagar national highway in Udhampur on Wednesday in which two jawans were killed.
The militant, who had taken three persons hostage in a school at a nearby village, was arrested after an operation was launched by the army and the police.
TV channels initially reported that he was 20-year Kasim Khan and that he came across the border from Pakistan. Danish Rana IG Jammu, later told NDTV that the captured militant's name was Usman and that he was from Faislabad in Pakistan.
The other militant was shot dead in the attack which began around 7.30 am and lasted for five hours. The militants hurled grenades and opened fire on the convoy when it reached Samroli near Udhampur on its way from Jammu to Srinagar.
Reports said the attack took place a short while after a batch of pilgrims to the Himalayan shrine of Amarnath passed the spot. Army and police rushed to the spot and the entire area was cordoned off immediately after the firing began.
