Iran arrests alleged opposition supporters after video circulates

Iranian authorities have arrested a number of people accused of appearing in a rare video waving the flag of an outlawed opposition group, state television said Sunday.

Videos circulating online in recent days showed individuals riding motorbikes on empty streets in Iran while waving the white-and-red banner of the banned People's Mujahedin Organisation of Iran (MEK).

On Sunday, state television said authorities had identified and arrested "all the individuals who appeared in this clip" and that they were "associated" with MEK, without specifying how many.

It said the motorcade had been travelling near the city of Karaj, west of Tehran, but it was not clear when the footage was recorded.

Founded in the 1960s in opposition to Iran's then Western-backed shah, the MEK was outlawed after the 1979 Islamic revolution and later fought alongside Saddam Hussein's forces during the Iran-Iraq war.

The group has for decades advocated regime change in Iran from abroad, while Tehran has accused its members of cooperating with its arch-enemy, Israel.

Iran has been at war with the United States since February 28, when US-Israeli strikes killed the Islamic republic's supreme leader Ayatollah Ali Khamenei along with senior military officials.

Iran retaliated with attacks across the region as the conflict spread.
