Humiliated by the killing of a top nuclear scientist, Iranian officials sought this week to rewrite the attack as an episode of science fiction: Israel had executed him entirely by remote control, spraying bullets from an automated machine gun propped up in a parked Nissan without a single assassin on the scene. Even hard-liners mocked the new spin. "Why don't you just say Tesla built the Nissan? It drove by itself, parked by itself, fired the shots and blew up by itself?" one hard-line social media account said. "Are you, like us, doubting this narrative?" Since the killing of the scientist on Friday, contradictory reports in the official news media about the escape or even existence of a hit team -- along with assertions of prior warnings from the Interior Ministry about the attack -- revealed tensions between competing Iranian intelligence agencies as each sought to dodge blame for an egregious security lapse.

TEHRAN, Iran (AP) -- Iran's supreme leader on Saturday demanded the "definitive punishment" of those behind the killing of a scientist who led Tehran's disbanded military nuclear program, as the Islamic Republic blamed Israel for a slaying that has raised fears of reignited tensions across the Middle East. After years of being in the shadows, the image of Mohsen Fakhrizadeh suddenly was to be seen everywhere in Iranian media, as his widow spoke on state television and officials publicly demanded revenge on Israel for the scientist's slaying. Israel, long suspected of killing Iranian scientists a decade ago amid earlier tensions over Tehran's nuclear program, has yet to comment on Fakhrizadeh's killing Friday. However, the attack bore the hallmarks of a carefully planned, military-style ambush, the likes of which Israel has been accused of conducting before. The attack has renewed fears of Iran striking back against the U.S., Israel's closest ally in the region, as it did earlier this year when a U.S. drone strike killed a top Iranian general.

The E.U. supports the Iranian nuclear deal as the Trump administration announces new sanctions. Iran's Revolutionary Guard on Saturday threatened to avenge the killing of its top general, saying it would go after everyone responsible for the January U.S. drone strike in Iraq. The guard's website quoted Gen. Hossein Salami as saying, "Mr. Our revenge for martyrdom of our great general is obvious, serious and real." FILE: Chief of Iran's Revolutionary Guard Gen.

Iran on Saturday said it had detained an Iranian-American leader of a little-known, California-based opposition group for allegedly planning a 2008 attack on a mosque that killed 14 people and wounded over 200 others. Iran's Intelligence Ministry also asserted that the detained man, Jamshid Sharmahd of the Kingdom Assembly of Iran, planned more attacks around the Islamic Republic amid heightened tensions between Tehran and the United States. Mr. Sharmahd's reported arrest comes as relations between the U.S. and Iran remain inflamed in the wake of President Donald Trump's 2018 decision to withdraw America from the 2015 multinational nuclear deal. In January, a U.S. drone strike killed a top Iranian general in Baghdad. Iran responded by launching a ballistic missile attack on U.S. soldiers in Iraq that injured dozens.

On June 30, US Secretary of State Mike Pompeo's address to the UN Security Council calling for an arms embargo on Iran to be extended was expected to dominate the international news agenda. However, Iran's judiciary stole the morning's headlines by issuing an arrest warrant for Donald Trump the day before. Tehran prosecutor Ali Alqasimehr said on Monday that Trump, along with more than 30 others accused of involvement in the January 3 drone attack that killed Iran's top general, Qassem Soleimani, face "murder and terrorism charges". The prosecutor added that Tehran asked Interpol for help in detaining the US president. The same day, the US special envoy for Iran, Brian Hook, denounced the warrant as a "propaganda stunt" at a press conference in the Saudi capital, Riyadh.

KYIV – A leaked recording of an exchange between an Iranian air-traffic controller and an Iranian pilot purports to show that authorities immediately knew a missile had downed a Ukrainian jetliner after takeoff from Tehran, killing all 176 people aboard, despite days of denials by the Islamic Republic. Ukraine President Volodymyr Zelenskiy acknowledged the recording's authenticity in a report aired by a Ukrainian television channel Sunday night. In Tehran on Monday, the head of the Iranian investigation team, Hassan Rezaeifar, acknowledged the recording was legitimate and said it was handed over to Ukrainian officials. After the Jan. 8 disaster, Iran's civilian government maintained for days that it didn't know the country's paramilitary Revolutionary Guard, answerable only to Supreme Leader Ayatollah Ali Khamenei, had shot down the aircraft. The downing of the jetliner came just hours after the Guard launched a ballistic missile attack on Iraqi bases housing U.S. forces in retaliation for an earlier American drone strike that killed the Guard's top general, Qassem Soleimani, in Baghdad.

WASHINGTON – The House Ethics Committee is warning lawmakers not to share doctored images or videos that could "erode public trust, effect public discourse, or sway an election," guidance that comes during a proliferation of online misinformation in the run-up to the 2020 elections. In a memo sent to House members Tuesday, the committee said lawmakers or staffers could be found in violation of House ethics rules and subject to disciplinary proceedings for posting content intended to mislead the public. "Members have a duty, and a First Amendment right, to contribute to the public discourse," the authors of the memo wrote. "However, manipulation of images and videos that are intended to mislead the public can harm that discourse and reflect discreditably on the House." It's the first time the committee has admonished members of Congress on the use of fake images and audio on social media, though the new guidelines may be difficult to enforce because of a loophole allowing fake images when used for satire or parody.

DUBAI, UNITED ARAB EMIRATES – Iran is not ruling out negotiations with the United States even after an American drone strike that killed a top Iranian general, the country's foreign minister said in an interview released Saturday. Mohammed Javad Zarif told Germany's Der Spiegel magazine that he would "never rule out the possibility that people will change their approach and recognize the realities," in an interview conducted Friday in Tehran. There has been growing tension between Washington and Tehran since in 2018, when President Donald Trump pulled the United States out of the nuclear deal with Iran. The U.S. has since reimposed tough sanctions that have crippled Iran's economy. But Zarif suggested Iran was still willing to talk, though reiterated his country's previous demand that first the U.S. would have to lift sanctions.

TEHRAN – An Iranian lawmaker on Tuesday offered a $3 million reward to "anyone who kills" U.S. President Donald Trump to avenge the assassination of a top general, the semi-official news agency ISNA reported. Ahmad Hamzeh, a little-known member of the Majlis, made the offer on behalf of the people of Kerman, the hometown and final resting place of storied commander, Qassem Soleimani. "We will give $3 million to anyone who kills Trump," Hamzeh, who represents Kahnouj county near the southeastern city of Kerman, was quoted as saying by ISNA. He did not say who would pay the bounty offer, which comes a month ahead of a parliamentary election. Soleimani, one of the most popular public figures in Iran, was killed on Jan. 3 in a U.S. drone strike outside Baghdad airport.

DUBAI, UNITED ARAB EMIRATES – A flurry of diplomatic visits and meetings crisscrossing the Persian Gulf have driven urgent efforts in recent days to defuse the possibility of all-out war after the U.S. killed Iran's top military commander. Global leaders and top diplomats are repeating the mantra of "de-escalation" and "dialog," yet none has publicly laid out a path to achieving either. The United States and Iran have said they do not want war, but fears have grown that the crisis could spin out of Tehran's or Washington's control. Tensions have careened from one crisis to another since President Donald Trump withdrew the U.S. from Iran's nuclear deal with world powers. The U.S. drone strike that killed Revolutionary Guard Gen. Qassem Soleimani and a senior Iraqi militia leader in Baghdad on Jan. 3 was seen as a major provocation.
