Wreaths were laid at the Major Purshottam memorial in the Badami Bagh cantonment headquarters of the Army here.
"In a solemn and poignant ceremony held at the Badami Bagh cantonment, all ranks of the Public Relations Office paid rich tributes to Major P Purushottam and five soldiers who were killed in a Fidayeen (suicide) attack on this day in 1999," a defence spokesman said.
Major Purushottam, who was posted as a Public Relations Officer (Defence) along with five of his comrades, fought militants who had launched the attack on his office on November 3, the spokesman said.
