“It would be a very serious mistake fraught with unpredictable consequences,” Lavrov said on Monday.
“Military intervention only leads to a multiple rise in casualties and human suffering,” he was quoted as saying by AFP.
Lavrov added that there can be no military solution to the Iranian nuclear issue.
The Russian foreign minister’s remarks come as Israel has renewed its aggressive rhetoric against Iran. Israeli President Shimon Peres threatened on Sunday that an attack on Tehran is becoming “more and more likely.”
Israeli Prime Minister Benjamin Netanyahu and Defense Minister Ehud Barak have reportedly been lobbying to persuade the Israeli cabinet to militarily strike Iran over its nuclear program.
Last week, the Israeli regime test-fired a ballistic missile which is widely believed is capable of carrying nuclear warheads.
Meanwhile, Iranian officials have promised a crushing response to any military strike against the country.
Washington and Tel Aviv have repeatedly threatened Tehran with the “option” of a military strike, based on their allegation that Iran’s nuclear program may include a covert military aspect.
Iran insists that it has the right to develop and acquire nuclear technology for peaceful purposes as a signatory to the Nuclear Non-Proliferation Treaty and a member of the International Atomic Energy Agency.
