The International Day for Mine Awareness is observed on April 4. It was declared by the United Nations General Assembly in 2005 and has been marked since 2006.
The day spreads awareness about the dangers of landmines and supports their removal. Mine action includes detecting and clearing mines, helping victims and making land safe for use. Landmines, unexploded ordnance (UXO) and improvised explosive devices (IEDs) can kill or injure civilians long after a war ends. The theme for 2026 is 'Invest in Peace; Invest in Mine Action'.
