Phnom Penh (FN), Jan 24 – Cambodian Mine Action Center (CMAC) said Tuesday that hundreds of students and monks will be evacuated as two dangerous chemical bombs left by the U.S during Vietnam war--were found.

Heng Ratana, director general of CMAC said Tuesday that CMAC has found two chemical bombs-categorized as Chlorobenzalmalononitrile (CS), at a primary school and pagoda in Svay Rieng province, approximately 100km Southeast of Phnom Penh.

As planed, between 500 and 700 villagers, students and Buddhist monks will be evacuated from the sites early next month, he said.

Chlorobenzalmalononitrile (CS) can harm children’s respiratory system and have other biological effects.

According to CMAC, the chemical compound used to be found in three other provinces – Svay Rieng, Prey Veng, and Mondulkiri.

There were approximately 3 million tons of bombs dropped in Cambodia from 1963-1975 with the excuse to kill Vietnamese invaders but it actually killed 500,000 Cambodians, according to former U.S President Bill Clinton.
