UNITED NATIONS / DUBAI - Iran summoned the Swiss envoy on Thursday to protest against what it called “baseless” US claims that Tehran has tried to interfere with the 2020 presidential election in November.

“Iran’s strong rejection of American officials’ repetitive, baseless and false claims was conveyed to the Swiss ambassador...As we have said before, it makes no difference for Iran who wins the US election,” Foreign Ministry spokesman Saeed Khatibzadeh told state TV.

Switzerland represents US interests in Iran because Washington and Tehran have no diplomatic ties.

On Wednesday, a spokesman for the Iranian mission to the United Nations (UN) said Iran has no interest in interfering in the US election.

"Unlike the US, Iran does not interfere in other country's elections. The world has been witnessing US own desperate public attempts to question the outcome of its own elections at the highest level," said Alireza Miryousefi, while denying the allegations against Iran to ABC News.

The outlet had reported that senior US national security officials alerted the American public Wednesday that Iran and Russia had both obtained voter data in their efforts to interfere in the 2020 US election.

"These accusations are nothing more than another scenario to undermine voter confidence in the security of the US election, and are absurd. Iran has no interest in interfering in the US election and no preference for the outcome. The US must end its malign and dangerous accusations against Iran," the spokesperson said.

Tensions have risen between longtime foes Tehran and Washington since 2018, when US President Donald Trump exited Iran’s 2015 nuclear deal and stepped up sanctions on Tehran.
