Khamenei said, "The money for carrying out the plot was provided by Saudi, one of the rich states in the Persian Gulf region".
Khamenei also described the recent wave of violence that hit some areas of the country as "fireworks and vicious acts".
The comments come after a day, after the government reportedly arrested its former president Mahmoud Ahmadinejad in south-central Iran's Shiraz for making provocative statements at a rally, that instigated the unrest.
Iran is still witnessing a wave of demonstrations, being held in many cities across the country as people took to raising anti-government slogans, over alleged corruption and rising prices that plagued the people of the country earlier this week.
Khamenei on last week, also said that he blamed the country's 'enemies' to instigate the ongoing anti-government protests. However, he said that he would name them at a 'suitable time'.
"The people of Iran are finally acting against the brutal and corrupt Iranian regime. All of the money that President Obama so foolishly gave them went into terrorism and into their "pockets", Trump wrote on Twitter.
The authorities have blocked two popular social media apps- Telegram and Instagram, as a security measure.
The official death toll in the anti-government protests is, as of now, 20. Thousands of protesters have been arrested in the last few days.
