Colombia president to call for suspension of coca plant spraying

BOGOTA (Reuters) - Colombia's president will ask the government to suspend aerial fumigation of coca plants used to make cocaine, he said on Saturday, amid signs the weed killer used may cause cancer, a decision which could complicate the country's war on drugs.

President Juan Manuel Santos said on Saturday he will ask the National Narcotics Council to suspend crop dusting flights after the World Health Organization (WHO) said in March that glyphosate they disperse is "probably carcinogenic to humans".
