RNA - "The US is itself origin of most criminal acts across the globe," Amoli Larijani said.
He reiterated that the world has not forgotten the US' massacre in Vietnam, Iraq and Afghanistan.
The Iranian judiciary chief also slammed Washington for its support for Israel in a bid to oppress the Palestinians and the Yemeni people.
"Threats will boost the great Iranian nation's commitment for resistance against the distrustful government of the US, Amoli Larijani added.
In a relevant development in Monday, Iranian President Hassan Rouhani communicated a law earlier approved by the parliament to the foreign ministry to confront the US measures in the region.
'The law to confront the US human rights violation and adventurist and terrorist acts in the region' was communicated to the foreign ministry in a letter yesterday.
Iran has always blasted the US for supporting the terrorist groups in the region, stressing that Washington is using terrorism instrumentally to meet its interests.
"The US and certain regional states speak loudly about fighting against terrorism, but today it has become clear that they support the terrorists using different means," Iranian Parliament Speaker Ali Larijani said in June.
"Actually, playing with terrorism is the US strategy," he added.
Also, in February, former Iranian Defense Minister Brigadier General Hossein Dehqan lashed out at Washington for creating, supporting and nurturing the terrorist groups, specially the ISIL, in the region.
"The entire world has today accepted that the ISIL Takfiri-terrorist groups are the biggest threat to regional and international security," General Dehqan said, addressing a forum in Tehran.
Noting that US President Donald Trump has admitted that the former US administration has founded the Takfiri terrorism, he lambasted Washington for raising terrorism allegations against Tehran which has fought against the terrorist groups with all its power and has been a victim of terrorism itself.
