A lawyer says a Washington Post reporter jailed in Iran faces four charges, including an espionage charge.

Lawyer Leila Ahsan, who represents reporter Jason Rezaian, told the Post on Monday that the correspondent also faces charges of "conducting propaganda against the establishment," ''collaborating with hostile governments" and "collecting information about internal and foreign policy and providing them to individuals with malicious intent."

Rezaian has been the Post's correspondent in Tehran since 2012 and has been held by Iranian authorities since July 22. He was born and spent most of his life in the United States, and holds Iranian and American citizenship. Iran doesn't recognize dual nationalities for its citizens

Rezaian's family, the Post and the U.S. State Department repeatedly have called for the journalist's immediate release.
