Iran frees three detained foreigners

Iran's judiciary has freed three foreign nationals, who were arrested during Wednesday's rally commemorating the 30th anniversary of the US Embassy takeover in Tehran.

"Three foreign nationals, one Canadian and two Germans, who were arrested on Wednesday have been freed," the Islamic Republic News Agency (IRNA) quoted Tehran's prosecutor general Abbas Jafari-Dolatabadi as saying late Friday.

According to the prosecutor, a Danish student was also detained that same day.

"We have asked the relevant authorities to present us with documents explaining the purposes of his presence and his mission in Iran," he added. "The required measures will be taken after receiving the documents."

Dolatabadi also confirmed the arrest of an Iranian reporter working for the Agence France-Press (AFP) while covering a rally commemorating the 30th anniversary of the US Embassy takeover in Tehran.

"Some other detainees, half of them women, were also freed on Friday night," he went on to say.

On Wednesday tens of thousands of Iranians took to the streets as part of an annual event to mark the storming of the American embassy in Tehran more than three decades ago.

In 1979, Iranian revolutionary students took over the US Embassy in Tehran and held 52 Americans hostage for 444 days, following the popular overthrow of Iran's US-backed monarch.

The event, which was sparked after Iran's last monarch, Mohammad-Reza Pahlavi, was issued a US visa, led to unilateral US sanctions against the Islamic Republic. Tehran and Washington have had no diplomatic ties since then.
