More than 2,000 people have been killed during the violent crackdown by security forces on protests in Iran, a human rights group has said, as President Trump promised Iranians that help was "on its way", BBC reported. 

The US-based Human Rights Activists News Agency (HRANA) reported that it had so far confirmed the killing of 1,850 protesters, 135 people affiliated with the government and nine uninvolved civilians as well as nine children over the last 17 days despite an internet blackout.

An Iranian official also told Reuters that 2,000 people had been killed but that "terrorists" were to blame, according to BBC.
