The blowback over the US killing of a top Iranian general mounted on Sunday, 5 January as Iran announced it will no longer abide by the limits contained in the 2015 nuclear deal and Iraq's Parliament called for the expulsion of all American troops from Iraqi soil.
The twin developments could bring Iran closer to building an atomic bomb and enable the Islamic State group to stage a comeback in Iraq, making the Middle East a far more dangerous and unstable place.
Iranian state television cited a statement by President Hassan Rouhani's administration saying the country would not observe limits 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.
In Iraq, meanwhile, lawmakers voted in favor of a resolution calling for an end to the foreign military presence in the country, including the estimated 5,200 US troops stationed to help battle Islamic State extremists.
The bill is subject to approval by the Iraqi government but has the backing of the outgoing prime minister.
In yet another sign of rising tensions and threats of retaliation over the deadly airstrike, the US-led military coalition in Iraq said it is putting the battle against IS on hold to focus on protecting its own troops and bases.
The string of developments capped a day of mass mourning over Iranian Maj. Gen. Qassem Soleimani, killed in a US drone strike in Baghdad on Friday, 3 January. Hundreds of thousands of people flooded the streets in the cities of Ahvaz and Mashhad to walk alongside the casket of Soleimani, who was the architect of Iran's proxy wars across the Mideast and was blamed for the deaths of hundreds of Americans in suicide bombings and other attacks.
The US State Department had no immediate comment on Iran's announcement.
As for Iraq, Secretary of State Mike Pompeo was asked before the vote the whether the US would comply with a troop-withdrawal request but would not answer directly.
He said the US “is prepared to help the Iraqi people get what it is they deserve and continue our mission there to take down terrorism from ISIS and others in the region.”
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 President Donald 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 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 percent, 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 immediately 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 Iraq, where the airstrike has been denounced as a violation of the country's sovereignty, Prime Minister Adel Abdul-Mahdi said that the government has two choices: End the presence of foreign troops or restrict their mission to training Iraqi forces. He called for the first option.
The majority of about 180 legislators present in Parliament voted in favor of the troop-removal resolution. It was backed by most Shiite members of Parliament, who hold a majority of seats. Many Sunni and Kurdish legislators did not show up for the session, apparently because they oppose abolishing the deal.
A US pullout could not only undermine the fight against the Islamic State but could also enable Iran to increase its influence in Iraq, which like Iran is a majority-Shiite country.
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. ”
The US 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 centers like Tel Aviv could be targeted should the US attack Iran.
Iranian state TV estimated that millions of mourners came out in Ahvaz and Mashhad to pay their respects to Soleimani.
The casket moved slowly through streets choked with mourners wearing black, beating their chests and carrying posters with Soleimani's portrait. Demonstrators also carried red Shiite flags, which traditionally symbolize both the spilled blood of someone unjustly killed and a call for vengeance.
The processions marked 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.
Soleimani's remains will go to Tehran and Qom on Monday for public mourning processions. He will be buried in his hometown of Kerman.
