Iranian Interior Minister Abdolreza Rahmani Fazli criticised the European countries for their lack of assistance to Iran's drug campaign.

The European countries have even avoided supplying Iran with x-ray systems and sniffer dogs in fight of drug campaign, Iranian Interior Minister Abdolreza Rahmani Fazli told reporters in a press conference in Tehran on Sunday.

"I always tell the European officials at international circles that they claim to be against money-laundering, but the turnover of drug money in their banks stands at $50bln", Iranian Interior Minister added.

Rahmani Fazli said that drugs, refugees and terrorism are international problems and the international bodies should actively help those countries which are in the frontline of such wars, including Iran.

The anti-drug squads of the Iranian Law Enforcement Police have intensified their countrywide campaign against drug-trafficking through staging long-term systematic operations since 2010.

The Iranian police officials maintain that drug production in Afghanistan has undergone a 40-fold increase since the US-led invasion of the country in 2001.

Afghan and western officials blame Washington and NATO for the change, saying that allies have "overlooked" the drug problem since invading the country more than 16 years ago.
