Six Iranian protesters were indicted yesterday on assault charges in connection with a brief takeover at the Iranian Interests Section of the Algerian Embassy here in August in which five people were held hostage and one demonstrator suffered a gunshot wound.

A D.C. Superior Court grand jury also indicted Akbar Nouchedehi, who had been a hostage, on a charge of assault with intent to kill in the shooting of the demonstrator and for carrying a pistol without a license.

Police said Nouchedehi allegedly wounded a man identified as Mohammed Shamirza in the back as the protesters walked out of the offices, with their hands above their heads, prepared to surrender to police after 20 minutes of negotiations.

A group of 24 demonstrators, who support deposed Iranian president Abol Hassan Bani-Sadr and oppose Ayatollah Ruhollah Khomeini, stormed the embassy at 2139 Wisconsin Ave. NW on Aug. 7, sprayed the offices with red and black paint and burned at least one picture of Khomeini, according to police.

The six demonstrators indicted yesterday previously pleaded guilty in U.S. District Court, as did the 18 other protesters, to separate charges of forcible entry of the embassy as part of a plea bargain in which they agreed to pay for property damages.

Charged with misdemeanor assault are Abdoreza Afhami, Ahmad Aghababa, Hamid Reza Arabzadeh, Mohsen Dianatkhah, Ali Reza Khairghadam and Asgar Momenzadeh.
