The campaign was organised ahead of an international conference of countries parties to the Ottawa Convention on the Prohibition of Anti-Personnel Mines, which is scheduled to take place in Zagreb from 28 November to 2 December.
The campaign, dubbed "Warning, Land Mines!", was launched on 9 November and will last until 3 December. It costs an estimated five million kuna (approximately 675,000 euros), which has entirely been raised through donations.
