“I am convinced that this is the hand of the United States, that Washington is behind the terrorist attack, and this is precisely a terrorist attack, since a blow was struck on a sovereign country,” RIA Novosti quoted him as saying.
According to Tsekov, Washington seeks to weaken Iran and, in the long term, "to achieve a change of power in Tehran."
This is not the first act of US aggression against Iran, as well as against other sovereign states, he added.
Earlier it was reported about a powerful explosion in Iran.
The Wall Street Journal reported that Israel attacked the military plant of the Iranian Ministry of Defense in the city of Isfahan with the help of drones.
According to the Al Arabiya TV channel, American aircraft were involved in the drone attack on a military facility in Isfahan.
