18 July 2011 :

Iranian authorities have hanged another 30 prisoners at Vakilabad Prison in Mashhad on drug-related charges, says the International Campaign for Human Rights in Iran.
The campaign cites “local knowledgeable sources” saying 12 prisoners were executed on Wednesday June 29 and another 18 were hanged on Sunday July 3.
The International Campaign for Human Rights in Iran say the executions once again were carried out in secret and en masse, with no prior notification of families and attorneys and no official announcement from the judiciary.
