Thousands of protesters have clashed with authorities as they took to the streets of Los Angeles for a third night in response to United States President Donald Trump's extraordinary deployment of the National Guard. Sunday's protests in Los Angeles, a sprawling city of 4 million people, were centred in several blocks of the city centre. It was the third and most intense day of demonstrations against Trump's immigration crackdown in the region, as the arrival of about 300 National Guard troops spurred anger and fear among many residents. The troops were deployed specifically to protect federal buildings, including the Metropolitan Detention Center where protesters concentrated. The crowds blocked a major highway and set fire to self-driving cars.

Ukraine's Foreign Minister Andrii Sybiha said Russia had "responded" to Kyiv's audacious drone attack that destroyed Russian heavy bombers at airfields in Siberia last weekend by attacking civilians and civilian infrastructure in Ukraine. Russia's Ministry of Defence said its forces had carried out the strikes, which targeted military and military-related targets in response to what it called Ukrainian "terrorist acts" against Russia. Western military aviation experts told the Reuters news agency that Russia will take years to replace the nuclear-capable bomber planes that were hit in Ukrainian drone strikes on airfields in Siberia. Russia's National Guard said it killed a man as he tried to prepare a drone attack on a military site in Russia's Ryazan region, southeast of Moscow. Russian air defence units intercepted and destroyed 82 Ukrainian drones over Russian territory, including the Moscow region, Russia's Defence Ministry said early on Saturday.

Bellwether, a new group inside "X," the innovation lab that is part of Google's parent company Alphabet, has developed tech that can ingest photos taken at an angle by airplanes, compare them with satellite imagery and maps, and automatically identify locations, roads, buildings and other important infrastructure. Bellwether has been testing the tech with the National Guard, which will deploy it in time for the summer wildfire season, said Nirav Patel, a program manager with the Defense Innovation Unit (DIU), a Pentagon unit that helps the military integrate commercial technology and that helped organize the partnership.

Jack Texeira was enlisted in the Air National Guard - where he had access to top secret material. He has been accused of leaking sensitive documents about the war in Ukraine and other issues, allegedly to impress his friends on the Discord group where he spent much of his time.

As fires get larger and more dangerous, various government and private agencies have turned to AI to detect, and potentially predict wildfires. The National Guard has been carrying out reconnaissance flights in California during the late summer and fall for the pew years, but now the drones used to carry out these flights have received upgrades with AI algorithms intended to automatically generate maps of fires within a particular region. Creating fire maps is an incredibly difficult process that requires data analysis to map constantly changing fires as they move over rugged terrain. Both air and ground observations are used to make fire maps, and fire maps are typically only updated once every day or so. Large fires can move as far as 15 miles during a single day, as witnessed by some of the fires this fire season.

HULMAN FIELD AIR NATIONAL GUARD BASE, Ind. -- New systems in the development of artificial intelligence (AI) technology for domestic response were tested by managers of the Johns Hopkins Applied Physics Lab (JHU-APL) and the Joint Artificial Intelligence Center's (JAIC) Humanitarian Assistance Disaster Relief (HADR) program. The testing took place Nov. 2 at an Indiana Unclassified Processing, Assessment and Dissemination (UPAD) site at the 181st Intelligence Wing. Intelligence Analysts assigned to the Indiana Air National Guard's 181st Intelligence Wing, 137th Intelligence Squadron UPAD, were chosen to assist in new developmental programs expected to be launched in the next year. This was the first time any of these programs or systems were tested by a UPAD site and UPAD analysts. "The AI technology uses commercial satellite static imagery, National Oceanic and Atmospheric Administration (NOAA) imagery, and MQ-9 full-motion video (FMV). Utilization of Synthetic Aperture Radar (SAR) imagery is in the works as well," said Tech. "The four lines of effort include route analysis, damage assessment, flood water detection, and fire perimeter analysis," he said.

"The JAIC is working to bring critical AI detection technology to the first responders who bravely battle wildfires. Increased use of AI will reduce response timelines, increase situational awareness, and save more American lives." Last year's California wildfire season was the deadliest and most destructive in United States history. More than 8,500 fires burned across nearly 1.9 million acres in the state of California and resulted in more than $16.5 billion in damage. Cumulatively, the wildfires were the costliest natural disaster of 2018, as well as one of the deadliest.

From New York National Guard: "A bomb disposal robot, piloted from a distance, examines a downed drone with explosive material tethered to it during training." Looks like that bomb was ... frozen in its tracks. Look, I'm not going to beat the lede from the New York National Guard, so here it is in full: The remote-controlled robot bumped across the divots of the grassy field until it reached the downed toy drone. Its camera gazed up and down as it examined the explosive device nearby, in a Taylor Swift lunch box tethered to the drone. The drone, the robot, the lunch box, and the explosive device were part of an exercise called Raven's Challenge.
