Five days, five stories that moved a border, a coastline, or a front line — plus a map from our library that puts one of them in scale.

1. US and Iran trade strikes for a fifth straight day as the fight over the Strait of Hormuz reignites

Washington reimposed a naval blockade on Iranian ports and struck Greater Tunb Island — one of several small islands in the strait that Iran and the UAE have disputed for decades — along with targets near Bushehr's nuclear plant (NYT, BBC). Iran fired back at US bases in Bahrain, Kuwait and Jordan and threatened to halt all Middle East energy exports (The Guardian, Al Jazeera). Trump briefly floated, then dropped, a 20% toll on ships transiting the strait (NYT, BBC). Barely 33km wide at its narrowest, the strait carries roughly a fifth of the world's oil — and controlling it is a lever neither side wants to give up.

2. Argentina's World Cup banner reignites the Falklands/Malvinas dispute

After beating England 2-1 in the World Cup semi-final, Argentina's players unfurled a banner reading "Las Malvinas son Argentinas" — the Falklands are Argentine — a direct reference to the 1982 war between the two countries (BBC, The Guardian, Al Jazeera, NYT). FIFA's Stadium Code of Conduct bars political messaging, and Argentina now faces possible disciplinary action. The islands' sovereignty, contested since rival 18th-century colonial claims and fought over in a ten-week war forty-four years ago, remains an open wound that a football match can reopen in seconds.

3. Gibraltar's border fence with Spain comes down

Days after the two sides agreed to lift border controls, Gibraltar and Spain marked the change with a symbolic midnight ceremony, and crowds crossed the frontier without checks for the first time (BBC — the only outlet in our feeds to cover it). The line dates to the 1713 Treaty of Utrecht, when Britain took Gibraltar from Spain, and Madrid has sealed it before, most notably during a 1969-1985 blockade under Franco. Sovereignty hasn't changed hands, but one of Europe's oldest disputed frontiers just got physically softer.

4. Zelenskyy dismisses his defence minister as Ukraine escalates its Black Sea campaign against Crimea

President Volodymyr Zelenskyy removed Mykhailo Fedorov, the minister credited with building Ukraine's drone warfare programme, in a government reshuffle after six months in the post (The Guardian, NYT). The change landed as Ukraine intensified a campaign to sever Russia's sea routes to Crimea, striking around 20 Russian vessels and hitting Black Sea oil tankers (BBC, NYT), while Russian strikes killed 14 people across several Ukrainian regions and hit Kyiv again just after Ukraine and the EU signed a new drone-cooperation deal (Al Jazeera, Deutsche Welle). Since Russia's 2014 annexation, the sea routes feeding Crimea have become their own front in the war.

5. Deportations strain the India-Bangladesh border

India has stepped up removals of people it says are Bangladeshi migrants living in the country illegally, and Bangladesh is pushing back, leaving people stranded in the no-man's-land along the frontier (NYT — the only outlet in our feeds reporting it). The border, drawn hastily during 1947 Partition and running more than 4,000km, already cuts through villages, farmland and a scatter of enclaves that took decades to fully resolve. Migration enforcement is now testing a line that has rarely been calm, and rarely fully settled, since the day it was drawn.

The data behind it

Our World in Data's "Military Spending as a Share of GDP, 2025" map puts this week's Ukraine story in scale. Ukraine is shaded almost black — the single darkest country on the map — spending upward of 40% of GDP on defence, unmatched anywhere else on earth. Russia sits in the next band down, deep red across its full breadth from the Baltic to the Pacific. The rest of the map tells its own stories: Saudi Arabia and its Gulf neighbours glow orange-red against the backdrop of this week's Iran war, and Algeria is nearly as dark as Ukraine, a reflection of its own long-running regional tensions. Most of the world — the Americas, sub-Saharan Africa, East Asia — sits in pale cream, spending under 2% of GDP. War concentrates military budgets as sharply as it concentrates headlines.
