Sierra Leone’s Instructor Manual (2007) provides: “It is prohibited to … [u]se anti-personnel landmines.”

Sierra Leone voted in favour of the UN General Assembly resolutions supporting a ban on anti-personnel mines adopted in 1996, 1997 and 1998. In September 1997, the Foreign Minister, Shirley Gbujuma, told Human Rights Watch that the government in exile would sign the Ottawa Convention on Anti-Personnel Mines.
