NEW DEHI: Indian police said on Thursday an investigation had been launched into the suspected suicide of three young sisters over concerns that they were heavily “influenced” by games and movies online that they were later denied access to.

Local media reported the sisters, aged 12, 14 and 16 had jumped from their home on Wednesday in the city of Ghaziabad on the outskirts of the country’s capital.

Concern among experts and regulators has grown in recent years that too much screen time and addictive algorithms are harming child development, sparking authorities, including in India, to push for social media bans for children and teens.

“(An) investigation is underway based on the suicide note and their phones,” Nimish Patil, a senior police official, told AFP on Thursday.

Police in India routinely investigate the factors leading up to suspected suicides.

The sisters had been “denied access” to K-Pop music and Korean games and movies that they had previously played and watched online.

“They were influenced by Korean culture: K-pop music, games and movies,” Patil said.

He added that the family also appeared to be under financial distress.

Their father had recently taken away their devices and barred them from watching Korean dramas and playing online games, the Indian Express newspaper reported. AFP could not immediately reach family members for comment.

Korean culture has surged in popularity, especially among young people, in India over the past decades, beginning with rapper Psy’s 2012 hit “Gangnam Style” and expanding through K-Pop and streaming platforms packed with Korean dramas.

The case has sparked debate in India with intense media coverage highlighting concerns about young people’s skyrocketing online exposure deepening mental health vulnerabilities.

Two Indian states recently said they were preparing the ground for banning children from using social media.

Internationally, governments have been exploring social media restrictions for children and teenageers, led by Australia, which banned the networks for under-16s in December.

French lawmakers in the country’s lower house last month passed a bill that if confirmed by its Senate will ban social media use by under-15s and bar mobile phones from high schools.

• Lapse of New Start treaty ends half-century of nuclear restraint.
• Russia criticises US for not agreeing to extend warhead limits.
• Moscow says neither side is bound any more by treaty provisions.

MOSCOW: Russia and the United States are no longer bound by any limits on the size of their strategic nuclear arsenals after their last arms control treaty expired on Thursday with no agreement between them on what should come next.

The New Start treaty, which set limits on each side’s missiles, launchers and strategic warheads, was the last in a series of nuclear agreements stretching back more than half a century to the depths of the Cold War.

Security experts say its expiry risks ushering in a new arms race that will also be fuelled by China’s rapid nuclear build-up.

Russian President Vladimir Putin had proposed that Moscow and Washington agree to adhere to the treaty’s key provisions for one more year, but US President Donald Trump did not make any formal response.

Trump says he wants a better deal that will also bring in China. But Beijing refuses to negotiate with the other two countries because it has only a fraction of their warhead numbers – an estimated 600, compared to around 4,000 each for Russia and the US

In a statement late on Wednesday, hours before New Start lapsed, Russia criticised what it called the “mistaken and regrettable” US approach.

It said Moscow’s assumption now was that the treaty no longer applied, and both sides were free to choose their next steps.

Russia “remains prepared to take decisive military-technical countermeasures to mitigate potential additional threats to national security”.

But it will act responsibly and is open to diplomacy to seek a “comprehensive stabilisation of the strategic situation,” the statement said, striking a balance between assertiveness and restraint.

Trump made no statement as the treaty expired. The White House said this week that Trump would decide the way forward on nuclear arms control, which he would “clarify on his own timeline”.

UN chief says nuclear risk is highest in decades

Strategic nuclear weapons are the long-range systems that each side would use to strike the other’s capital, military and industrial centres in the event of a nuclear war.

They differ from so-called tactical nuclear weapons that have a lower yield and are designed for limited strikes or battlefield use.

In the absence of a treaty framework that provides stability and predictability, analysts say each side will find it harder to read the other’s intentions. That could lead to a spiral in which each feels the need to keep on adding weapons, based on worst-case assumptions about what the other is planning.

Within a couple of years, each could deploy hundreds more warheads beyond the New Start limit of 1,550, experts say.

“Transparency and predictability are among the more intangible benefits of arms control and underpin deterrence and strategic stability,” said Karim Haggag, director of the Stockholm International Peace Research Institute.

“Without them, relations between nuclear weapon states are likely to be more crisis prone – especially with artificial intelligence and other new technologies adding complexity and unpredictability to escalation dynamics and a worrying lack of diplomatic and military communication channels between the USA and both China and Russia.”

UN Secretary-General Antonio Guterres said the dissolution of decades of achievement in arms control “could not come at a worse time – the risk of a nuclear weapon being used is the highest in decades.”

He urged Russia and the US to resume negotiations without delay to agree “a successor framework that restores verifiable limits, reduces risks, and strengthens our common security”.

WASHINGTON: The New York City Health Department on Wednesday said it has joined the World Health Organisation’s global outbreak response network following President Donald Trump’s withdrawal of the US from the UN health agency.

Why’s important

Following the Republican president’s decision to pull the US out of the WHO, some Democratic leaders have made their regions join the WHO’s Global Outbreak Alert and Response Network (GOARN) in defiance of Trump. New York City Mayor Zohran Mamdani has been critical of the president’s policies.

California Governor Gavin Newsom and Illinois Governor JB Pritzker, both Democrats, have also said their states will join the WHO’s global outbreak response network. The network responds to public health events around the world, such as pandemics and disease outbreaks, and comprises of more than 360 technical institutions.

Key quotes

“By joining GOARN, New York City gains access to a global network of over 360 institutions and organisations that respond to acute public health events with the deployment of staff and resources to affected countries,” the NYC Health Department said in a statement.

“Infectious diseases know no boundaries, and nor should the information and resources that help us protect New Yorkers,” New York City Acting Health Commissioner and Chief Medical Officer Michelle Morse added.

Context

The US formally left the WHO last month after completing a one-year waiting period following an executive order that Trump signed in January 2025.

Since taking office, Trump has withdrawn the US from dozens of global and UN entities, saying they do not benefit Washington. His steps have been condemned by health and human rights experts.
