TEHRAN, Iran (AP) -- An Iranian general who replaced the leader killed by a U.S. airstrike in Baghdad vowed Sunday to take revenge as Tehran abandoned the remaining limits of its 2015 nuclear deal with world powers in response to the slaying.
Esmail Ghaani's threat comes as the blowback over the U.S. killing of top Iranian general Qassem Soleimani mounted Sunday with Iraq's parliament calling for the expulsion of all American troops from Iraqi soil.
The three developments could bring Iran closer to building an atomic bomb, see an proxy or military attack launched by Tehran against America and enable the Islamic State group to stage a comeback in Iraq, making the Middle East a far more dangerous and unstable place.
Adding to the tensions, President Donald Trump threatened to demand billions of dollars in compensation from Iraq or impose "sanctions like they've never seen before" if it goes through with expelling U.S. troops.
Ghaani made his remarks in an interview with Iranian state television aired Monday.
"God the almighty has promised to get his revenge, and God is the main avenger. Certainly actions will be taken," Ghaani said.
Ghaani now serves as the head of the Revolutionary Guard's Quds Force, an expeditionary arm of the paramilitary organization answerable only to Iran's Supreme Leader Ayatollah Ali Khamenei. As Soleimani's longtime deputy, Ghaani has been sanctioned by the U.S. since 2012 for his work funding its operations around the world, including its work with proxies in Iraq, Lebanon and Yemen.
Those proxies likely will be involved in any operation targeting U.S. interests in the Mideast or elsewhere in the world.
Already, the U.S. Embassy in Saudi Arabia warned Americans "of the heightened risk of missile and drone attacks." In Lebanon, the leader of the Iranian-backed militant group Hezbollah said Soleimani's killing made U.S. military bases, warships and service members across the region fair game for attacks. A former Iranian Revolutionary Guard leader suggested the Israeli city of Haifa and others could be targeted should the U.S. attack Iran.
"We promise to continue down martyr Soleimani's path as firmly as before with help of God, and in return for his martyrdom we aim to get rid of America from the region," Ghaani said.
On the nuclear deal, Iranian state television cited a statement by President Hassan Rouhani's administration saying the country would not observe the nuclear deal's restrictions on fuel enrichment, on the size of its enriched uranium stockpile and on its research and development activities.
"The Islamic Republic of Iran no longer faces any limitations in operations," a state TV broadcaster said.
German Chancellor Angela Merkel, French President Emmanuel Macron and British Prime Minister Boris Johnson specifically urged Iran to "withdraw all measures" not in line with the 2015 agreement that was intended to stop Tehran from pursuing its atomic weapons program.
Iran insisted that it remains open to negotiations with European partners over its nuclear program. And it did not back off from earlier promises that it wouldn't seek a nuclear weapon.
However, the announcement represents the clearest nuclear proliferation threat yet made by Iran since Trump unilaterally withdrew from the accord in 2018 and reimposed sanctions. It further raises regional tensions, as Iran's longtime foe Israel has promised never to allow Iran to produce an atomic bomb.
Iran did not elaborate on what levels it would immediately reach in its program.Tehran has already broken some of the deal's limits as part of a step-by-step pressure campaign to get sanctions relief. It already has increased its production, begun enriching uranium to 5% and restarted enrichment at an underground facility.
While it does not possess uranium enriched to weapons-grade levels of 90%, any push forward narrows the estimated one-year "breakout time" needed for it to have enough material to build a nuclear weapon if it chose to do so.
The International Atomic Energy Agency, the United Nations watchdog observing Iran's program, did not respond to a request for comment. However, Iran said that its cooperation with the IAEA "will continue as before."
Foreign Ministry spokesman Abbas Mousavi earlier told journalists that Soleimani's killing would prompt Iranian officials to take a bigger step away from the nuclear deal.
"In the world of politics, all developments are interconnected," Mousavi said.
Soleimani's killing has escalated the crisis between Tehran and Washington after months of back-and-forth attacks and threats that have put the wider Middle East on edge. Iran has promised "harsh revenge" for the U.S. attack, while Trump has vowed on Twitter that the U.S. will strike back at 52 targets "VERY FAST AND VERY HARD. "
He doubled down on that threat Sunday, dismissing warnings that targeting cultural sites could be a war crime under international law.
"They're allowed to kill our people. They're allowed to torture and maim our people. They're allowed to use roadside bombs and blow up our people. And we're not allowed to touch their cultural sites? It doesn't work that way," Trump told reporters.
On Sunday, hundreds of thousands of mourners accompanied the coffin carrying Soleimani's remains in the Iranian cities of Ahvaz and Mashhad. A similar procession was expected in Qom and Tehran on Monday. Tens of thousands already filled the streets of the Iranian capital early Monday morning.
Mourners wearing black beat their chests and carried posters with Soleimani's portrait. Demonstrators also unfurled red Shiite flags, which traditionally symbolize both the spilled blood of someone unjustly killed and a call for vengeance.
The processions mark the first time Iran honored a single man with a multi-city ceremony. Not even Ayatollah Ruhollah Khomeini, who founded the Islamic Republic, received such a processional with his death in 1989. Soleimani on Monday will lie in state at Tehran's famed Musalla mosque as the revolutionary leader did before him.
He will be buried in his hometown of Kerman.
