South Korean authorities launched an investigation on Tuesday after three people died during a car test at a Hyundai Motor plant in the city of Ulsan, police told Reuters.

The two Hyundai researchers and one Hyundai contractor were found unconscious in a car at around 3:00 p.m. while they were testing it in a "chamber," according to Hyundai's labour union.

South Korean media reports said the three had suffocated.

A police officer in Ulsan said the police and the labour ministry were investigating the incident, including its cause.

A fire department official told Reuters that it first received a report at 3:17 pm that the accident happened at Hyundai's No.4 factory.

"Hyundai Motor Company is deeply saddened by the incident that occurred at our plant in Ulsan, South Korea," Hyundai said in a statement, saying it would "cooperate fully with all relevant authorities to determine the cause of this incident."

The Ulsan plant is Hyundai's biggest manufacturing facility, with its own port and an annual production capacity of 1.4 million vehicles, including exports of 1.1 million units.

In November last year, Hyundai Motor broke ground on a 2 trillion won ($1.44 billion) plant in Ulsan dedicated to making electric vehicles in South Korea, as the automaker accelerated a shift away from petrol-powered cars.

Apple on Tuesday launched its new generation of the iPad mini packed with AI features including writing tools and an improved Siri assistant, as the iPhone maker races to boost its devices with artificial-intelligence capabilities, Reuters reported.

The new iPad mini is powered by Apple's A17 Pro chip, which is used in the iPhone 15 Pro and Pro Max models. With a six-core central processing unit, the A17 Pro would boost CPU performance by 30% compared to the current generation iPad minis and is central to running Apple Intelligence, Apple's AI software.

Apple said it would roll out the first set of AI features in the U.S. version of the English language this month through a software update with iPadOS 18.1.

The features will be available for iPads with A17 Pro or M1 chips and later generations, Apple said, adding it will roll out additional features including image-generation tools, Genmoji and ChatGPT-powered capabilities over the next several months, read the report.

Apple in September unveiled its long-awaited, AI-boosted iPhone 16 lineup, but with the AI features still in test mode, the company failed to excite some investors while early sales data raised some questions around demand.

Still, research firm Canalys on Monday said the iPhone 16 would help Apple's sales in the fourth quarter and drive momentum into the first half of 2025, after Apple reached a record high third-quarter shipments.

The iPad mini, starting at $499, is available for pre-orders starting on Tuesday and will begin arriving to customers and Apple store locations next week, Apple said.

Iran has sent two locally made satellites to Russia to be put into orbit by a Russian space vehicle, the semi-official news agency Tasnim reported on Saturday, in the latest space cooperation between the two U.S.-sanctioned countries.

The development of Kowsar, a high-resolution imaging satellite, and Hodhod, a small communications satellite, is the first substantial effort by Iran's private space sector, the report said.

Russia sent Iranian satellites into orbit in February and in 2022, when U.S. officials voiced concern over space cooperation between Russia and Iran, fearing the satellite will not only help Russia in Ukraine but also help Iran monitor potential military targets in Israel and the wider Middle East, Reuters reported.

Kowsar could be used in agriculture, natural resource management, environmental monitoring, and disaster management, Tasnim said.

Hodhod is designed for satellite-based communications and could be used in remote areas with little access to terrestrial networks.

In September, Iran carried out its second satellite launch, this year using a rocket built by its Revolutionary Guards. 

The launch came as the United States and European countries accuse Tehran of transferring ballistic missiles to Russia that could be used in its war with Ukraine. Iran has denied this.
