constantly needs to be managed because people will endeavour to abuse it
Along the invisible line that divides Ireland from Northern Ireland, a decades-old freedom of movement has quietly become one of Europe's most significant migration corridors. Irish government data now suggests that nearly nine in ten asylum seekers entered the Republic not through airports or ports, but by walking across a border designed for citizens, not controlled for strangers. A knife attack in Belfast by a Sudanese refugee has brought this slow-building tension into sharp relief, forcing two governments to reckon with the gap between an open border's promise and its unintended consequences.
- Ireland's asylum applications surged from roughly 5,000 a year before 2019 to 18,500 in a single year, with up to 90% of applicants believed to have crossed undetected over the Northern Ireland land border.
- A Sudanese refugee's knife attack in Belfast — following a journey from Sudan through Paris and Dublin — triggered two nights of communal violence and brought police reinforcements from Great Britain to Northern Ireland.
- The UK Home Office reports apprehending over 900 immigration offenders abusing the open border in the past year, yet without physical checkpoints neither government can confirm the true scale of crossings.
- Both governments are racing to revive a post-Brexit returns agreement, but the deal has been nearly dormant — only one person has been returned under it — and legal and political obstacles remain formidable.
- Northern Ireland's political landscape is fracturing under the pressure, with unionist leaders calling for the border to be closed entirely while analysts warn that any border measure carries its own deep historical weight.
Between 2022 and 2024, asylum applications in Ireland surged to 18,500 in a single year — a dramatic rise for a small nation that had seen roughly 5,000 annually before 2019. The more striking detail is how people arrived: approximately 90% did not come through Dublin airport or a southern port, but crossed the open land border between Northern Ireland and the Republic, a line with no checkpoints and no way to count who passes through.
The Common Travel Area, a longstanding agreement allowing free movement between Ireland and Britain, has become a well-worn migration route. Irish government data shows that the vast majority of asylum applicants made their first application in person at the International Protection Office in Dublin — not at any border post — suggesting they had already entered undetected. The UK Home Office reported apprehending more than 900 immigration offenders abusing the open border in the past year alone, yet neither government can say with certainty how many have crossed.
The issue sharpened dramatically following a knife attack in Belfast. Hadi Alodid, a 30-year-old Sudanese refugee who had travelled from Sudan to Paris to Dublin before claiming asylum in Belfast in 2023, has been charged with attempted murder. The attack set off two nights of communal violence and brought police reinforcements from Great Britain to Northern Ireland, intensifying calls on both sides of the border for action.
Both governments moved quickly to respond. Northern Ireland Secretary Hilary Benn spoke with Irish ministers, and officials on both sides said they are working to revive a post-Brexit returns agreement — largely dormant since Ireland's high court ruled the UK's Rwanda policy made it an unsafe third country. With the UK having since redesignated itself as safe, officials say the returns process can now restart, though only one person has been returned under the agreement so far.
The political temperature in Northern Ireland has risen sharply. Deputy First Minister Emma Little-Pengelly raised questions about immigration checks, while DUP leader Gavin Robinson called for the border to be closed entirely. Taoiseach Micheál Martin defended the Common Travel Area as a net positive but acknowledged it 'constantly needs to be managed.' The tension at the heart of the story remains unresolved: an agreement built to connect two neighboring peoples has become, in an era of mass migration, a door that neither government quite knows how to close — or whether closing it would cost more than leaving it open.
The numbers tell a stark story. Between 2022 and 2024, asylum applications in Ireland surged to 18,500 in a single year—a dramatic shift for a small island nation that had seen only about 5,000 such applications annually before 2019. But the most striking figure is where these people arrived: roughly 90% did not step off a plane or ferry at Dublin airport or a southern port. Instead, they walked across the invisible line that separates Northern Ireland from the Republic, moving through an open border that has no checkpoints, no gates, no way to count who passes through.
The Common Travel Area, a decades-old agreement that allows Irish and British citizens to move freely between the two islands, has become a route that asylum seekers are using in large numbers. Irish government data released this week shows the arrangement is being exploited in both directions, but the flow appears heavier toward Ireland. In 2025 and 2026 so far, 88% and 90% of asylum applicants made their first application in person at the International Protection Office in Dublin—not at border posts or airports, but at an office in the capital, suggesting they had already entered the country undetected.
The UK Home Office reported overnight that it had apprehended more than 900 "immigration offenders" abusing the open land border in the past year alone. Yet without physical checks on either side, neither government can say with certainty how many people have crossed illegally. Ireland's then justice minister, Helen McEntee, stated publicly in 2024 that 80% of asylum seekers were arriving over the land border. Department of Foreign Affairs and Trade officials later said their assessment, drawn from staff experience and interviews with applicants, was that "a significant proportion" had entered this way.
The issue has taken on new urgency following a knife attack in Belfast on Monday. Hadi Alodid, a 30-year-old Sudanese refugee, has been charged with attempted murder. His journey illustrates the route: Sudan to Paris to Dublin, then a bus to Belfast where he claimed asylum in 2023. The attack triggered two nights of violence and brought police reinforcements from Great Britain to Northern Ireland on Thursday. The incident has intensified political pressure on both sides of the border to address what some critics now call a "back door to Britain."
Government officials have moved quickly to respond. The Northern Ireland secretary, Hilary Benn, spoke with Irish justice minister Jim O'Callaghan and foreign minister McEntee. Both governments said they are working to revive a post-Brexit returns agreement that would allow asylum seekers to be sent back across the border—though the deal has been largely dormant, with only one person returned from the UK to Ireland so far. The agreement stalled after Ireland's high court ruled that the UK's Rwanda asylum policy meant it could not be considered a legally safe third country. Now, with the UK having redesignated itself as safe, officials say arrangements will be put in place to restart the returns process.
The political temperature has risen sharply in Northern Ireland. Emma Little-Pengelly, the deputy first minister, said there were "questions to be asked" about immigration policy and the checks happening in Dublin. Democratic Unionist leader Gavin Robinson has called for the border to be closed entirely. Katy Hayward, a professor of political sociology at Queen's University Belfast, noted that border issues are inherently contentious in Northern Ireland, but added that the intensity has grown "post-Brexit" as unionist leaders struggle to balance public anger with the need to work within existing institutions.
Ireland's taoiseach, Micheál Martin, defended the Common Travel Area as positive for Irish and British citizens but acknowledged it "constantly needs to be managed" because people will "endeavour to abuse it." The statement captures the core tension: an agreement designed to facilitate movement between neighboring countries has become a vulnerability in an era of mass migration, and closing it entirely would carry its own political and practical costs. What remains unclear is whether the revived returns agreement will prove effective, or whether the open border will continue to be the path of least resistance for those seeking asylum in Ireland.

La Conversación del Hearth Otra perspectiva de la historia
Why does the Common Travel Area matter so much here? It sounds like a bureaucratic detail.
It's the absence of a detail that matters. There are no checkpoints, no gates, no way to count who crosses. For asylum seekers, that means entering Ireland without being recorded at a border post. They can then apply for protection once they're already inside.
So the 90% figure—does that mean 90% of people are breaking the law?
Not necessarily. Once they're in Ireland and apply for asylum, they're in the system. The question is whether they entered illegally or exploited a loophole in how the CTA works. The governments can't verify the exact numbers because there's no way to check.
The knife attack seems to have changed the conversation overnight.
It crystallized something that was already a political problem into a security problem. A refugee from Sudan had traveled through multiple countries and ended up in Belfast. When violence followed, it became impossible for politicians to ignore the border issue.
Is the returns agreement actually going to work?
That's the real question. It's been dormant for years—only one person sent back. The legal obstacles are real. But now both governments are saying they'll try again. Whether they can actually move people back across the border, and whether it will reduce the numbers, is still unknown.
What happens to the people already here?
They're in the asylum system. Some will be approved, some rejected. But the immediate political focus is on stopping new arrivals from using the land border route. The people already in Ireland are less urgent to the conversation than preventing future crossings.
