"These statements (by Kerry) are for consumption of a group of audience of a specific media in the region, but in the meantime it is the violation of international law and the charter of the United Nations," Afkham underlined.
Kerry said in an interview in Geneva on Thursday that the military option was still on the table if Iran did not live up to its nuclear commitments under the Geneva deal.
On Friday, Deputy Chief of Staff of the Iranian Armed Forces for Cultural Affairs and Defense Publicity Brigadier General Massoud Jazzayeri downplayed the US and its allies' war rhetoric against Iran, and said they don't dare to attack Iran because they have no hope of victory in such a war.
In response to Kerry's comments, the senior Iranian commander said that the US government knows that the military option against Iran is not practical.
The United States has long stressed that military action is a main option for the White House to deter Iran's progress in the field of nuclear technology.
Iran has warned that in case of an attack by either the US or Israel, it will target 32 American bases in the Middle-East and close the strategic Strait of Hormuz.
An estimated 40 percent of the world's oil supply passes through the waterway.
