British Prime Minister Sir Keir Starmer is currently embroiled in a significant international controversy, as a “crimes against humanity” complaint has been lodged against him at the United Nations. This move comes amid heightened tensions following an attempted Iranian missile strike aimed at Diego Garcia, a strategically vital island in the Indian Ocean.
The complaint, which specifically names Starmer, was submitted by the attorney general of the Chagossian government. It concerns the removal of four individuals who had returned to the island, highlighting the ongoing grievances of the Chagossian people who were displaced decades ago.
The legal action coincides with calls from the Chagossian leadership for robust relations with the United States. In a statement to Fox News Digital, they emphasized the importance of their alliance with the U.S., describing Washington as a crucial partner in maintaining global security.
Diego Garcia, home to a U.S. military base, has long been a pivotal asset for military operations. Notably, in October 2001, a U.S. B-2 Spirit bomber from Whiteman Air Force Base in Missouri refueled there after conducting airstrikes in Afghanistan during Operation Enduring Freedom.
On March 20, Iran launched two ballistic missiles toward Diego Garcia from a distance of over 2,300 miles. Although the missiles did not hit their target, the incident underscores the strategic significance of the base and highlights regional security concerns.
Chagossian leaders have since backed a continued U.S. presence, with First Minister Misley Mandarin saying they want to “uphold the 1966 agreement and consider the U.S. as a brother in arms for global security.”
The 1966 agreement allowed the U.S. to use Diego Garcia for defense purposes, initially for 50 years.
“The desire of the Chagossian government is to have a positive relationship with the U.S. and an ongoing presence on Diego Garcia of the U.S. military,” Tumbridge also told Fox News Digital.

Meanwhile, Tumbridge’s U.N. submission claims U.K. actions risk the “forced depopulation” of the Chagos Islands.
Expulsions began in 1968, when about 2,000 residents were removed, culminating in 1973, and in February the U.K. issued new removal orders to four Chagossians who had returned to the islands.
The filing calls the situation “forced displacement” that could constitute “a crime against humanity by forced depopulation of a territory.”
It warns the British government of a “fresh crime now” that could complete a decades-long erasure of the Indigenous population, stating, “The removal of these four persons would result in the total physical erasure of the Chagossian people,” potentially “amounting to ethnic cleansing.”

“The BIOT commissioner accepted that the Chagossians were wronged in the past,” Tumbridge said Wednesday.
“How can the U.K. prime minister, who claims to value the rule of law and human rights, not want to right that wrong and let the people return to their islands?”
The filing also comes as the U.K. considers transferring sovereignty of the Chagos Islands to Mauritius.
This followed a 2019 International Court of Justice opinion, while preserving the Diego Garcia base under a 99-year lease.
President Donald Trump criticized the proposed handover, and the U.K. has since paused legislation to formalize the deal, with ministers saying it has become “impossible to agree at a political level.”
The legislation was expected to be included in the King’s speech outlining the next parliamentary session’s agenda.

A UK government spokesperson told Fox News Digital that the Diego Garcia military base is “crucial to the security of the UK and our key allies, and to keeping the British people safe.Â
“There are ongoing legal proceedings before the BIOT courts. Various UK and international courts have found that there is no right of abode on the Archipelago,” the spokesperson said in a statement.
Responding to the statement, Tumbridge claimed Starmer’s government was “misleading” people and warned a “serious fight” is on the horizon.
“Sadly, the British Government is misleading people. No court anywhere has ever found ‘that there is no right of abode on the Archipelago.’ Tony Blair’s Government took away the right of abode and passed attempts to quash that law in court failed, until the Supreme Court of the BIOT ruled on March 31st and quashed it,” he said.
