Because of shifting storms and sweltering summers, Iran's capital faces a future "Day Zero" when the taps run dry. During the summer of 2025, Iran experienced an exceptional heat wave, with daytime temperatures across several regions, including Tehran, approaching 50 degrees Celsius (122 degrees Fahrenheit) and forcing the temporary closure of public offices and banks. During this period, major reservoirs supplying the Tehran region reached record-low levels, and water supply systems came under acute strain . By early November, the reservoir behind Amir Kabir Dam, a main source of drinking water for Tehran, had dropped to about 8 percent of its capacity . The present crisis reflects not only this summer's extreme heat but also several consecutive years of reduced precipitation and ongoing drought conditions across Iran.

This study presents a learning - based nonlinear algorithm for tracking control of differential - drive mobile robots. The Computed Torque Method (CTM) suffers from inaccurate knowledge of system parameters, while Deep Reinforcement Learning (DRL) algorithms a re known for sample inefficiency and weak stability guarantees. The proposed method replaces the black box policy network of a DRL agent with a gray box Computed Torque Controller (CTC) to improve sample efficiency and ensure closed loop stability. This ap proach enables finding an optimal set of controller parameters for an arbitrary reward function using only a few short learning episodes. The Twin Delayed Deep Deterministic Policy Gradient (TD3) algorithm is used for this purpose. Additionally, some controller parameters are constrained to lie within known value ranges, ensuring the RL agent learns physically plausible values. A technique is also ap plied to enforce a critically damped closed loop time response. The controller's performance is evaluated on a differential drive mobile robot simulated in the MuJoCo physics engine and compared against the raw CTC and a conventional kinematic controller.

For the past few years, governments across the world have paid close attention to conflicts in Ukraine and the Middle East. There, it is said, we see the first glimpses of what warfare of the future will look like, not just in terms of weaponry, but also in terms of new technologies and tactics. Most recently, the United States-Israeli attacks on Iran demonstrated not just new strategies of drone deployment and infiltration but also new vulnerabilities. During the 12-day conflict, Iran and vessels in the waters of the Gulf experienced repeated disruptions of GPS signal. This clearly worried the Iranian authorities who, after the end of the war, began to look for alternatives.

Gilan, Iran – The Israeli military used hundreds of fighter jets, armed drones and refuelling planes to attack Iran during its 12-day war backed by the United States, but it was also heavily assisted by operations launched from deep within Iranian soil. Just hours after the Israeli army and Mossad spy agency started their attacks before dawn on June 13, they released footage that appeared to have been recorded at night from undisclosed locations inside Iran. One grainy video showed Mossad operatives, camouflaged and wearing tactical gear including night-vision goggles, crouched in what looked like desert terrain, deploying weapons that aimed to destroy Iran's air defence systems to help pave the way for incoming attack aircraft. Others showed projectiles, with mounted cameras, descending to slam into Iranian missile defence batteries, as well as ballistic missile platforms. The projectiles appeared to be Spike missiles – relatively small, precision-guided anti-armour missiles that can be programmed to fly to targets that are out of their line of sight.

Kyiv, Ukraine – There is a Persian word millions of Ukrainians fear. Shahed – also spelled as Shaheed or Shahid, originally a Quranic term for "martyr" or "witness" – is the name given to the triangular, explosives-laden, Iranian-designed drones that became a harrowing part of daily life and death in wartime Ukraine. These days, they are assembled in the Volga-region Russian city of Yelabuga and undergo constant modifications to make them faster, smarter and deadlier during each air raid that involves hundreds of drones. Their latest Russian versions shot down in Ukraine earlier this month have artificial intelligence modules to better recognise targets, video cameras and two-way radio communication with human operators. "The word'Shahed' will forever be cursed in Ukrainian next to'Moscow' and'Putin'," said Denys Kovalenko, referring to Russian President Vladimir Putin. Kovalenko's face and arms were cut by glass shards after a Shahed exploded above his northern Kyiv neighbourhood in 2023.

The IDF said it had killed Izadi in a strike on an apartment in Qom, south of Tehran, in the early hours of Saturday. He had been in charge of the Palestine Corps of the Iranian Revolutionary Guards Corps's (IRGC) Quds Force, responsible for handling ties with the Palestinian armed groups. He was reportedly instrumental in arming and financing Hamas, and had been responsible for military co-ordination between senior IRGC commanders and Hamas leaders, the IDF said. In April 2024, Izadi narrowly survived an Israeli air strike targeting the Iranian consulate in Damascus, Syria - an attack that killed several high-ranking Quds Force commanders. Israel later on Saturday also claimed to have killed another Quds Force commander, Behnam Shahriyari in a drone strike as he was travelling in a car through western Iran.

Artificial intelligence could spark an accidental nuclear war, conflict experts fear. The Stockholm International Peace Research Institute (SIPRI), the world's leading organisation on nuclear assessments, said technologies like AI are aggravating the risk carried with growing global nuclear stockpiles. SIPRI pointed to China's rapidly growing stockpile, from 500 to 600 in a single year, as well as the imminent expiry of the final arms control treaty between the US and Russia, two nuclear-armed nations. The institute's director, Dan Smith, warned: 'One component of the coming arms race will be the attempt to gain and maintain a competitive edge in artificial intelligence (AI), both for offensive and defensive purposes. 'There are benefits to be found but the careless adoption of AI could significantly increase nuclear risk.'

Israel and Iran have carried out a new wave of attacks on key cities, fuelling fears of an all-out sustained war, with heavy exchanges now entering a third day. Iranian missiles struck northern Israel, killing at least three people and wounding 13 others, late Saturday into Sunday, according to Israeli media. Israel targeted the Iranian defence ministry headquarters in Tehran early Sunday, according to the semi-official Tasnim news agency. Iranian officials also said the Shahran oil depot, northwest of Tehran, was struck by Israel. Tasnim News said operational and rescue forces arrived at the scene and are still working to extinguish the fire.

The Mossad published footage of its operatives carrying out covert actions inside Iran prior to Israel's preemptive attack. Israel's overnight strike on Iran was not only one of the most ambitious aerial campaigns in recent history, it was the result of years of covert planning, surveillance and infiltration by Israeli intelligence. While dozens of fighter jets bombed nuclear and military targets across Iran early Friday morning, the groundwork had long been laid by Mossad agents working in lockstep with the Israeli military. Code-named "Am Kelavi" (Rising Lion), the preemptive operation was the product of unprecedented coordination between the Israeli air force, the Military Intelligence Directorate, Mossad and the country's defense industries. For years, they worked "shoulder to shoulder" to gather the intelligence files needed to eliminate Iran's most sensitive military and nuclear assets.

Russian President Vladimir Putin has told Donald Trump in a telephone conversation that Moscow would have to respond to the recent Ukrainian drone attacks, the US president said. Trump said on Wednesday that the two men "discussed the attack on Russia's docked airplanes, by Ukraine, and also various other attacks that have been taking place by both sides." Putin "did say, and very strongly, that he will have to respond to the recent attack on the airfields", Trump said in a social media post. Al Jazeera's Kimberly Halkett said that Trump described his 85-minute phone call with Putin as "a good conversation but not one that would lead to immediate peace". "You have to remember that Donald Trump, when he came into office, was very confident that he could end this war on day one, but here we are now in June and the fact is … this is far from resolved," she said from the White House.
