More than 100 pieces of unexploded ordnance were discovered and collected in Preah Sihanouk province on Wednesday before being handed over to bomb disposal experts.
Provincial police chief Choun Narin said 136 UXOs were found in places such as Sihanoukville, Prey Nob district and Stung Hav district.
He said that the UXOs found included 85mm, 82mm and 107mm rocket propelled grenades.
“All these UXOs were left since the war but they did not put anyone in danger when they were found,” Mr Narin said.
He added that his officials cooperated with Cambodian Mine Action Centre experts to take them away.
On Tuesday, 21 UXOs were found in a rice field in Preah Vihear province’s Chey Sen district and were destroyed at the scene.
The Cambodian Mine Action and Victim Assistance Authority says Cambodia will be mine-free by 2025, noting that the country had made significant progress in reducing mine-related casualties over the past 25 years.
Ly Thuch, senior minister and first vice-president of CMAA, said the organisation was confident unexploded ordnances that had haunted the nation since the Vietnam War would be cleared by 2025.
According to a CMAA report released in February, there were 39 accidents in 2017, a decrease of 46 percent compared with 72 cases in 2016.
The report added that of the 39 incidents, 20 cases were mine explosions and 19 were explosive remnants of war. When combined, these resulted in 58 casualties, a decrease of 30 percent compared with the 83 casualties in 2016.
