TEHRAN, Iran — Iran yesterday charged a detained Iranian-American academic with seeking to topple the ruling Islamic establishment, state-run television reported. Haleh Esfandiari, director of the Middle East Program at the Washington-based Woodrow Wilson Center for Scholars, has been held at Tehran’s notorious Evin Prison since early May.

Ms. Esfandiari, 67, came to Iran in December to visit her 93-year-old mother and was prevented from leaving the country when she tried to go home. State TV said she and the Wilson Center were conspiring together to topple the government by setting up a network “against the sovereignty of the country.” “This is an American-designed model with an attractive appearance that seeks the soft-toppling of the country,” state TV said.

The announcement was the first time Iran said it had officially charged Ms. Esfandiari with seeking to overthrow the ruling establishment, a severe security crime. It was not immediately clear when Ms. Esfandiari will stand trial.

The broadcast said Ms. Esfandiari confirmed during interrogations that her center “invited Iranians to attend conferences, offered them research projects, scholarships … and tried to lure influential elements and link them to decision-making centers in America.”
