Philippine senators opened an inquiry on Monday into the killings of more than 1,700 suspected drug dealers and users amid a crackdown spearheaded by President Rodrigo Duterte, with witnesses accusing some policemen of gunning down suspects or being involved in illegal drugs.
Sen Leila de Lima, who heads the Senate justice committee leading the investigation, said that she was worried about the widespread killings, and that law enforcers and vigilantes may be using the crackdown "to commit murder with impunity."
