A London-based Persian language channel on Monday said it had been forced to suspend live broadcasts after UK counter-terror police alerted its landlord to a potential threat from Tehran.
Manoto TV, which launched in 2010 and is an opposition channel popular with the Iranian diaspora, said the temporary suspension came as Iran faced one of the "most sensitive moments" in its history.
In recent months, Iran has seen mass anti-government protests in one of the largest challenges to the Islamic republic's clerical leadership in years, AFP reported.
"At a time when ... domestic and regional developments are unfolding at an unprecedented pace, the Islamic Republic's threats against freedom of speech -- aimed at suppressing independent reporting -- have intensified," Manoto TV said in a statement.
"Our landlord has informed us of their intention to terminate our tenancy following notification from the UK's Counter Terrorism Policing regarding a potential threat against us from the Islamic Republic of Iran Regime," the private broadcaster added.
Staff had been blocked from entering the building, resulting in the temporary suspension while alternative arrangements were put in place.
"Our priority is to return to live broadcasting from a safe and stable location as soon as possible," the station added.
Counter-terrorism police did not immediately reply to an AFP request for comment.
