Hanoi (VNA) - Filipino President Rodrigo Duterte said on September 22 that representatives from the United Nations (UN) and the European Union (EU) are welcome to probe the drug-related killings in the Philippines.

In a speech before troops and policemen in a military camp in Cagayan de Oro city, Duterte said he will write a letter to invite UN and EU officials for an investigation.

Previously, UN Secretary General Ban Ki-moon and the EU voiced concerns over the killings, which according to them, are a violation of human rights.

On September 20, Duterte slammed the EU parliament for issuing a statement calling for the government to "put an end to the current wave of extrajudicial executions and killings in the Philippines."

He also lambasted the UN, the US and its President Barack Obama for voicing concern over the spate of drug-related killings.

Statistics showed that more than 3,300 suspected drug paddlers and users have been killed since Duterte took office on June 30. The police have carried out nearly 19,000 police operations that led to the arrest of more than 18,000 suspects. More than 700,000 drug suspects have also surrendered.-VNA
