A senior Iranian official has threatened to allow the transit of illegal drugs through its territory to Europe should the West continue criticising the Islamic nation’s human rights record.

As Iran’s judiciary acknowledged that the country’s intelligence is investigating an American-Iranian academic for security crimes, US Secretary of State blasted the detention and called on Tehran today to immediately release Haleh Esfandiari.

The Iranian government has said that it agrees with the acquittal of a secret agent who had been charged with the killing of an Iranian-Canadian photojournalist, but Canada protested the verdict, hinting at further action to pressure the Middle Eastern country to find out the truth.
