US president Donald Trump has said that American control over Greenland is essential for the United States’ national security, describing it as “vital” for a planned air and missile defence system known as the Golden Dome.

In a social media post on Wednesday, Trump claimed the United States “needs Greenland for the purpose of National Security” and asserted that the Arctic island plays a key role in the proposed defence architecture. He further said that NATO would become “far more formidable and effective” if Greenland were under US control, adding that “anything less than that is unacceptable.”

Comments ahead of US-Denmark talks

Trump’s remarks came just hours before senior Danish and Greenlandic officials were scheduled to hold talks at the White House with US Vice President JD Vance and Secretary of State Marco Rubio. The discussions are focused on Greenland and broader security issues in the Arctic region.

Responding to US concerns, Denmark’s defence minister Troels Lund Poulsen said the country was increasing its military presence in Greenland. He also noted that Copenhagen was in discussions with allies regarding a stronger NATO footprint in the Arctic.

NATO role and strategic concerns

Trump said NATO “should be leading the way” in building the proposed multi-layer missile defence system. He warned that if the alliance did not act, rival powers could step in, stating that Russia or China might otherwise take the lead.

The US president has repeatedly spoken about taking control of Greenland, a strategically located and sparsely populated island that is an autonomous territory within the Kingdom of Denmark. His renewed comments underline continued US interest in the Arctic’s strategic importance amid rising global security competition.

Iran is reportedly preparing to execute an anti-government protester on Wednesday, triggering sharp warnings from US President Donald Trump, who said Washington would take “very strong action” if the hanging goes ahead. The development comes amid a sweeping crackdown on nationwide protests that rights groups say has killed more than 2,000 people.

According to human rights groups, 26-year-old Erfan Soltani, arrested last week during protests in Karaj near Tehran, has been sentenced to death and faces execution without a proper trial. Iranian authorities have not publicly detailed the charges or judicial process in his case.

Trump urges Iranians to keep protesting

Trump has publicly encouraged Iranians to continue protesting, saying “help is on its way”, while warning Tehran against executing demonstrators. Speaking to media, the US president said the United States would respond forcefully if Iran began hanging protesters arrested during the unrest.

Earlier, Trump posted messages urging people in Iran to continue demonstrations and said he had cancelled meetings with Iranian officials until the killing of protesters stops. He did not specify what assistance the US might provide or which meetings had been cancelled.

Iranian prosecutors have reportedly threatened capital punishment under charges of “moharebeh”, or waging war against God, for some detainees linked to the protests.

Rising death toll and reports from morgues

Rights groups say the crackdown has been one of the deadliest in recent years. According to activist organisations, the death toll has crossed 2,500, including civilians and members of the security forces. Iranian officials, however, have blamed what they described as “terrorists” for the deaths and have not provided a clear breakdown.

Videos circulating on social media show bodies lined up at the Kahrizak mortuary near Tehran, wrapped in black bags, as families search for missing relatives. Authorities have declared national mourning for security personnel killed during the unrest and announced mass funeral ceremonies in the capital.

Internet blackout and Starlink access

Iran has imposed a widespread internet blackout, now extending beyond five days, limiting communication and information flow. Amid the restrictions, SpaceX has reportedly waived subscription fees for its Starlink satellite service in Iran, allowing users with receivers to access the internet without payment, according to groups working to restore connectivity.

Some international phone links were partially restored, but reports indicate services remain unstable and limited.

Political tensions and international reaction

Iranian leaders have insisted that control has been restored following days of protests described as one of the biggest challenges to the clerical leadership since the 1979 revolution. Supreme Leader Ayatollah Ali Khamenei has hailed pro-government rallies as evidence that the protest movement has failed.

Senior Iranian officials have accused Trump and Israeli leadership of responsibility for violence in Iran. Meanwhile, Western leaders have condemned the use of force against protesters, with some warning that sustained repression could further destabilise the country.

Analysts note that while the protests represent a serious challenge to Iran’s leadership, the government retains powerful security and enforcement mechanisms, making the outcome uncertain.

Iran has acknowledged for the first time that close to 2,000 people, including members of the security forces, have been killed during two weeks of widespread protests across the country, according to an Iranian official.

The official said the deaths occurred amid violent clashes during nationwide unrest that erupted over worsening economic conditions. The figure marks the highest acknowledged toll so far from the current wave of demonstrations, which has posed one of the most serious internal challenges to Iran’s leadership in recent years.

Official blames “terrorists” for violence

According to the official, those described as “terrorists” were responsible for the deaths of both protesters and security personnel. However, no detailed breakdown was provided regarding how many civilians or security forces were killed.

Iran’s clerical leadership has accused the United States and Israel of instigating unrest in the country, alleging that external actors exploited public anger and escalated the demonstrations into violent confrontations.

Dual approach to protests

Authorities have attempted to balance their response by distinguishing between what they describe as legitimate protests over economic hardship and acts of violence. While acknowledging public frustration over living conditions, the government has simultaneously enforced a strict security crackdown to contain the unrest.

The protests are reported to be the most significant challenge to the Iranian establishment in at least three years and come at a time of heightened international pressure following military strikes by the US and Israel last year.

Rights groups cite arrests and casualties

Human rights organisations had earlier reported that hundreds of people were killed during the protests and said thousands were detained as security forces moved to suppress demonstrations across several cities.

The flow of information from inside Iran has been severely restricted due to communications curbs, including recent internet blackouts, making independent verification difficult.

Clashes captured on video

Despite restrictions, multiple videos circulating online have shown intense nighttime clashes between demonstrators and security forces. Some of these visuals, verified by media, depict gunfire, burning vehicles, and damage to buildings, highlighting the scale of violence during the unrest.
