A group campaigning to ban anti-personal mines in Sri Lanka says, it will take 15 more years to de-mine Sri Lanka's war-battered North and East regions. It criticised the government for not acceding to the Ottawa Convention also known as the Mine Ban Treaty. <br/><br/>After seven years of end of war with the LTTE, Sri Lanka remains the only country in the world to maintain that it's military installations should continue to be protected with landmines. Post-war Sri Lanka's mine causalities are civilians particularly children and women.
