Check out what's clicking on FoxNews.com Lebanon's Hezbollah leader vowed Sunday to shoot down any Israeli drones that enter Lebanese airspace from now on after one allegedly crashed and another exploded in Beirut overnight. Hassan Nasrallah said during a speech that one of the drones had been flying low among buildings and was clearly on a military "suicide mission," which he called "clear aggression." Officials of Iran-backed Hezbollah denied firing at the drones.

WASHINGTON – President Donald Trump invited Iranian Foreign Minister Mohammad Javad Zarif to the White House last month at the height of tensions between the two countries, The New Yorker magazine reported. The invitation, extended by Sen. Rand Paul with permission from the president, was turned down for now, The New Yorker reported Friday. Zarif said it was up to Tehran to decide on accepting it. Neither the White House nor the State Department responded to requests for comment on the report, which quoted U.S. and Iranian sources and what the magazine called a well-placed diplomat. Zarif told the magazine he would not want a White House meeting that yielded just a photo op and a two page statement afterwards, The New Yorker said.

WASHINGTON/DUBAI, UNITED ARAB EMIRATES - Iran said it had seized a British oil tanker in the Strait of Hormuz on Friday but denied Washington's assertion that the U.S. Navy had downed an Iranian drone nearby this week, as tensions in the Gulf region rose again. Britain said it was urgently seeking information about the Stena Impero tanker, which had been heading to a port in Saudi Arabia and suddenly changed course after passing through the strait at the mouth of the Gulf. The tanker's operator, Stena Bulk, said in a statement the ship was no longer under the crew's control and could not be contacted. Iran's state news agency IRNA quoted a military source as saying the vessel had turned off its tracker, ignored warnings from the Revolutionary Guard and was sailing in the wrong direction in a shipping lane. "We will respond in a way that is considered but robust and we are absolutely clear that if this situation is not resolved quickly there will be serious consequences," British Foreign Secretary Jeremy Hunt told reporters.

Iran's Revolutionary Guard claims the vessel was caught trying to smuggle Iranian oil to foreign ships; Trey Yingst reports. Iran on Friday denied President Trump's claim that a U.S. warship destroyed an Iranian drone near the Persian Gulf after it threatened the ship -- an incident that further escalated tensions between the countries. Trump said Thursday that the USS Boxer – which is among several U.S. Navy ships in the area – took defensive action after an Iranian drone came within 1,000 yards of the warship and ignored multiple calls to stand down. Trump blamed Iran for a "provocative and hostile" action and said the U.S. responded in self-defense. But Iran's foreign minister, Mohammad Javad Zarif, told reporters as he arrived for a meeting at the United Nations that "we have no information about losing a drone today."

TEHRAN - Iran said Tuesday it will further free itself from the 2015 nuclear deal in defiance of new American sanctions as U.S. President Donald Trump warned the Islamic republic of "overwhelming" retaliation for any attacks. Tensions between Iran and the U.S. have spiraled since last year when Trump withdrew the United States from the deal under which Tehran was to curb its nuclear program in exchange for relief from economic sanctions. The two arch-rivals have been locked in an escalating war of words since Iran shot down a U.S. surveillance drone in what it said was its own airspace, a claim the US vehemently denies. On Monday, Washington stepped up pressure by blacklisting Iran's supreme leader Ayatollah Ali Khamenei and top military chiefs, saying it would also sanction Foreign Minister Mohammad Javad Zarif later in the week. Tehran was defiant on Tuesday, saying the new US sanctions against Iran showed Washington was "lying" about an offer of talks.

DUBAI, UNITED ARAB EMIRATES - One person was killed and seven others were wounded in an attack by Iranian-allied Yemeni rebels on an airport in the kingdom Sunday evening as U.S. Secretary of State was on his way to the country for talks on Iran, Saudi Arabia said. Regional tensions have flared in recent days, The U.S. abruptly called off military strikes against Iran in response to the shooting down of an unmanned American surveillance drone. The Trump administration has vowed to combine a "maximum pressure" campaign of economic sanctions with a buildup of American forces in the region, following the U.S. withdrawal from the 2015 nuclear deal between Iran and world powers. A new set of U.S. sanctions on Iran are expected to be announced Monday. The Sunday attack by the Yemeni rebels, known as Houthis, targeted the Saudi airport in Abha.

Seated on the floor of a villa in northeast Tehran around a tablecloth spread with platters of saffron chicken and rice with barberries, about 30 officials of Iran's Islamic Revolutionary Guards Corps and guests gathered Thursday night for a prayerful celebration. "A special blessing for the commander who ordered the attack on the American drone and for the fighters who carried it out," a preacher declared, as recalled by one of the guests present, who said a raucous chorus of "amen" arose from the room. Their success earlier that day at shooting down an unmanned American Global Hawk surveillance drone (list price $131 million) surprised even some leaders of the Revolutionary Guards. They had wondered themselves whether they could hit an American target so high in the sky, according to the guest. In fact, the Revolutionary Guards sought to take out the drone in large part to prove they could do it, according to that guest and four other Iranians, including two senior current members.

WASHINGTON - U.S. military cyberforces launched a strike against Iranian military computer systems on Thursday as President Donald Trump backed away from plans for a more conventional military strike in response to Iran's downing of a U.S. surveillance drone, U.S. officials said Saturday. Two officials told The Associated Press that the strikes were conducted with approval from Trump. A third official confirmed the broad outlines of the strike. All spoke on condition of anonymity because they were not authorized to speak publicly about the operation. The cyberattacks -- a contingency plan developed over weeks amid escalating tensions -- disabled Iranian computer systems that controlled its rocket and missile launchers, the officials said.

Trump calls the strike a'foolish move'; national security correspondent Jennifer Griffin reports. It's time for the U.S. to take military action against Iran – not to start a war, but to blow some things up in retaliation for Iran shooting down a U.S. surveillance drone Thursday in international air space, just days after setting off explosives that damaged two oil tankers. President Trump gave Iran a pass after the recent tanker attacks. But instead of reassessing their strategy and trying to de-escalate tensions, the Iranians escalated significantly by shooting down the American drone – a high-flying unmanned aircraft that costs about $130 million. I don't see how President Trump can let Iran's latest attack pass without action if he expects Iran and other nations to respect the U.S. and not conclude they can attack our forces at will, without fear of retaliation.

TEHRAN - Iran's Revolutionary Guard shot down a U.S. surveillance drone Thursday in the Strait of Hormuz, marking the first time the Islamic Republic directly attacked the American military amid tensions over Tehran's unraveling nuclear deal with world powers. The two countries disputed the circumstances leading up to an Iranian surface-to-air missile bringing down the U.S. Navy RQ-4A Global Hawk, an unmanned aircraft with a wingspan larger than a Boeing 737 jetliner and costing over $100 million. Iran said the drone "violated" its territorial airspace, while the U.S. called the missile fire "an unprovoked attack" in international airspace over the narrow mouth of the Persian Gulf and President Donald Trump tweeted that "Iran made a very big mistake!" Trump later appeared to play down the incident, telling reporters in the Oval Office that he had a feeling that "a general or somebody" being "loose and stupid" made a mistake in shooting down the drone. The incident immediately heightened the crisis already gripping the wider region, which is rooted in Trump withdrawing the U.S. a year ago from Iran's 2015 nuclear deal and imposing crippling new sanctions on Tehran.
