Iran vows retaliation; Lt. Col. Daniel Davis, Walid Phares, and Rep. Mark Green react. A giant question mark hangs over the Middle East as the world waits to see what action Iran will take to retaliate for the long-overdue killing Friday morning of Iranian Gen. Qassem Soleimani in a drone strike ordered by President Trump. President Trump made the right decision in ordering Soleimani killed in Iraq. I've been arguing for four years that we ought to take out this dangerous enemy of the United States, who was responsible for the deaths of hundreds of Americans and wanted to kill many more. Thankfully, his killing days are over.

BAGHDAD – A fresh airstrike hit pro-Iran fighters in Iraq early Saturday, as fears grew of a proxy war erupting between Washington and Tehran a day after an American drone strike killed a top Iranian general. The killing of Quds Force commander Gen. Qassem Soleimani in Baghdad on Friday was the most dramatic escalation yet in spiralling tensions between Iran and the United States, which pledged to send more troops to the region -- even as President Donald Trump insisted he did not want war. Iran's ambassador to the United Nations, Majid Takht Ravanchi, told CNN that the killing was an "act of war on the part of the United States." A new strike on Saturday targeted a convoy belonging to the Hashed al-Shaabi, an Iraqi paramilitary network dominated by Shiite factions with close ties to Iran. The Hashed did not say who it held responsible but Iraqi state television reported it was a U.S. airstrike.

Fox News Flash top headlines for Jan. 3 are here. Check out what's clicking on Foxnews.com The U.S. men's soccer team announced Friday that it had canceled plans to train in Qatar later this month following the death of Iranian general Qassem Soleimani in an American drone strike. "Due to the developing situation in the region, U.S. Soccer has decided to postpone traveling to Qatar for the Men's National Team scheduled January training camp," the U.S. Soccer Federation said in a statement. "In the meantime, we are working on alternative arraignments in preparation for the match against Costa Rica on February 1 at Dignity Health Sports Park in Carson, Calif." "We are working with the Qatar Football Association to find an opportunity in the near future for our team to experience Qatar's world-class facilities and hospitality," the statement concluded.

Security has been upgraded at the Capitol after the U.S. drone strike that killed Iranian general Qassem Soleimani and prompted vows of retaliation from Iran. "Never underestimate the Iranians," one senior congressional source told Fox News. "They have a very strong presence here." Another source added, "We don't know what they're going to do," noting that "raising the security levels to some degree is prudent." Fox News is told one area of constant concern on Capitol Hill is a potential cyberattack.

After a U.S. airstrike kills Iranian Gen. Qassem Soleimani in Iraq, Secretary of State Mike Pompeo tells'Fox & amp; Friends' that President Trump's decision was necessary to deter further aggression. The U.N. special rapporteur on extrajudicial killing on Friday said the President Trump-approved drone strike against Qassem Soleimani, Iran's top general, violated international human rights law. In a lengthy Twitter thread, Agnès Callamard said that "outside the context of active hostilities, the use of drones or other means for targeted killing is almost never likely to be legal," adding that the U.S. would need to prove the person targeted constituted an imminent threat to others. She also took issue with the justification for using drones in another country on the basis of self-defense. "Under customary international law States can take military action if the threatened attack is imminent, no other means would deflect it, and the action is proportionate," she wrote.

Delivery robots incorporating AI are on the march, being deployed more widely on the ground, sometimes crowding sidewalks. Delivery robot providers include Starship Technologies, a startup created by Janus Friis and Ahti Heinla, founders of Skype. The company offers a general-purpose home delivery robot that today is an array of cameras and GPS sensors, but in the future will include microphones, speaker, and the ability via AI-driven natural language processing, to talk to customers. Since 2016, Starship has carried out 50,000 delivers in over 100 cities across 20 countries, according to an account in SingularityHub written by Dr. Peter H. Diamandis, the founder of Singularity University and the founder and executive chairman of the XPrize Foundation. Another startup delivery provider is Nuro, co-founded by Jiajun Zhu, an engineer who helped develop Google's self-driving car.

Will 2020 be the year of drone taxis? I'm going to peg it on'unlikely.' Drone taxi company EHang, which made its debut on the stock market in December 2019 with a public offering price of $12.50 per share, opened on its first trading day of 2020 in the $10 realm. But $10 might not be too shabby. While EHang stock hit as high as $13.70 per share, it has also dipped as low as $7.84 in the short timespan that it's been on the public market.

The timely knowledge of forage quality of grasslands is vital for matching the demands in animal feeding. Remote sensing (RS) is a promising tool for estimating field-scale forage quality compared with traditional methods, which usually do not provide equally detailed information. However, the applicability of RS prediction models depends on the variability of the underlying calibration data, which can be brought about by the inclusion of a multitude of grassland types and management practices in the model development. Major aims of this study were (i) to build forage quality estimation models for multiple grassland types based on an unmanned aerial vehicle (UAV)-borne imaging spectroscopy and (ii) to generate forage quality distribution maps using the best models obtained. The study examined data from eight grasslands in northern Hesse, Germany, which largely differed in terms of vegetation type and cutting regime. The UAV with a hyperspectral camera on board was utilised to acquire spectral images from the grasslands, and crude protein (CP) and acid detergent fibre (ADF) concentration of the forage was assessed at each cut.

A group of scientists in Canada have announced a new initiative to use drones to plant new trees cheaply and quickly in part of an effort to fight against the negative effects of climate change and deforestation. Called Flash Forest, the team began testing its drone delivery systems in August, with a test flight that saw them successfully plant 100 trees with a drone. Those results were so encouraging they've expanded their goals to use their specially designed drone systems to plant a billion new trees by 2028. 'Every year the planet loses 13 billion trees and regains less than half of that,' the team's Bryce Jones said in a fundraising video announcing the project. 'We started Flash Forest with the goal of healing the planet's lungs and taking that job seriously.
