Houthi militia have committed more than 2,200 breaches of international law, using land mines across 16 Yemen governorates, the Yemeni Coalition to Monitor Violations of Human Rights has reported.
The use of anti-personnel mines was outlawed by the 1997 Anti-Personnel Mine Ban Convention, which prohibits the development, production, stockpiling, transfer, and use of anti-personnel mines anywhere.
Hundreds of people have been killed and many more injured by mines planted by Houthi militia. Of the 2,220 violations 615 people were killed, many have included children under 16.
Mines have also been responsible for the damage and destruction of facilities such as bridges, wells and vehicles.
The report comes as the world marks International Day for Mine Awareness which falls on April 4.
The Yemeni Coalition to Monitor Violations of Human Rights has called on Houthi militia and ousted president Ali Abdullah Saleh to provide maps of minefields.
They have also demanded the cessation of the use of further mines - in accordance with international law. It also called for warning signs to be placed in areas which might contain random minefields to help prevent further deaths and injuries.
