The three, dubbed trouble-makers, were charged with threatening national security, the hard-line daily Khorassan wrote.
The charge acting against national security is a vague term which encompasses virtually all forms of social protests or actions against the ruling clerical authorities.
In January, Irans State Security Forces (SSF) arrested hundreds of individuals in the province of Khorassan Razavi as part of a crackdown of trouble-makers.
Agents of the SSF and VEVAK, Irans notorious secret police, arrested 770 individuals as part of the second phase of the Plan to Combat Trouble-makers, code-named Zafar 2, meaning victory.
Close to 300 of those arrested were to be formally tried in special Islamic courts set up to deal with the trouble-makers.
The Plan to Combat Trouble-makers was initially launched in Tehran in September and soon spread to cities and towns across the nation. Under the scheme, thousands were arrested within a period of several months on various charges such as racketeering and loansharking.
Iranian officials often refer to millions of unemployed young men, who are largely beset by frustration and despair, as trouble-makers.
