Iran unveiled an unmanned "ambassador of death" drone Sunday as a senior official warned that any "illogical move" by the U.S. against the Islamic Republic's nuclear program would bring attacks against U.S. interests worldwide.

President Mahmoud Ahmadinejad inaugurated the unmanned bomber that carries four cruise missiles and can fly up to 620 miles, saying, "The jet, as well as being an ambassador of death for the enemies of humanity, has a main message of peace and friendship."

The bomber, intended to "keep the enemy paralyzed in its bases," was unveiled a day after Iran fired up its first nuclear power reactor.

While boasting of progress in the nuclear arena and vowing to press forward with efforts Saturday, Iranian media on Sunday carried warnings to the West about interfering in the country's nuclear program.

A senior Revolutionary Guard official said Sunday that any military move against the nuclear program would be met by targeting Washington's interests across the globe.

"In case of any illogical move, the Islamic Republic's hands and advocates will be powerfully activated against the interests of the hegemonic system and U.S. bases outside the region," IRGC Politburo Chief General Yadollah Javani said, according to the semi-official Fars News Agency.

"If Americans make a strategic mistake and choose the military option against the Islamic Republic and our nation's interests, Iran will not confine its defense to the region," he said.

Iran's Judiciary chief accused the White House of threatening Tehran while demanding negotiations.

"The U.S. deceitfully speaks of negotiations concurrent with its threats and boycotts against Iran," Amoli Larijani said in a meeting with Iranian Judiciary officials Sunday in Tehran, according to Fars. "And this illogical approach is certainly unacceptable to Iran." 

Keeping with the trend of the day's comments out of Tehran, Ground Forces Commander Brig. Gen. Ahmad-Reza Pourdastan told the Islamic Republic News Agency that the country's military was ready to confront any "unwise or imprudent" actions.

In marking National Defense Industry Day, Ahmadinejad touted Iran's military as "a defense shield for all the oppressed nations."

“If an evil force decides to launch an attack on Iran out of ignorance, we will have to thwart their aggression even before they succeed to hit their targets,” Ahmadinejad said.

“No one is capable of striking Iran," he said. "The Zionists have only been imagining stuff about an attack.”
