Demonstrations broke out in Iran on Dec. 28 and have spread nationwide as protesters vent their increasing discontent over the Islamic Republic's faltering economy and the collapse of its currency. Dozens of people have been killed and thousands arrested as the daily protests have grown and the government seeks to contain them. While the initial focus had been on issues like spikes in the prices of food staples and the country's staggering annual inflation rate, protesters have now begun chanting anti-government statements as well.

Here is how the protests developed:

Iran closed its airspace to commercial flights for hours without explanation early Thursday as tensions remained high with the United States over Tehran's bloody crackdown on nationwide protests.

The closure ran for over four hours, according to pilot guidance issued by Iran, which lies on a key East-West flight route. International carriers diverted north and south around Iran, but after one extension, the closure appeared to have expired and several domestic flights were in the air just after 7 a.m.

Lebanese authorities have arrested a Syrian citizen who is suspected of sending money to fighters loyal to former Syrian President Bashar Assad in Syria, judicial officials said Wednesday.

Ahmad Dunia was detained in recent days in Lebanon's region of Byblos north of Beirut and is being questioned over alleged links to Assad's maternal cousin Rami Makhlouf as well as a former Syrian army general who left the country after Assad's fall in December 2024, the officials said.

Long lines beneath I.M. Pei's glass pyramid have become as much a part of the experience as the " Mona Lisa " itself.

Now the Louvre is putting a higher price on that pilgrimage, raising admission prices on Wednesday for most non-European visitors by 45% as it tries to shore up finances after repeated strikes, chronic overcrowding — and a brazen French Crown Jewels heist that shook the institution.

The Japanese and South Korean leaders agreed to deepen cooperation between their countries before they let loose with their own surprise cultural exchange in a surprise jam session drumming to K-pop hits.

The musical performance between Japanese Prime Minister Sanae Takaichi and South Korean President Lee Jae Myung followed Tuesday's summit in Japan's ancient capital of Nara, also Takaichi's hometown.

The European Union will dedicate most of a massive new loan program to Ukraine's military needs over the next two years while also injecting billions into its war-ravaged economy, European Commission President Ursula von der Leyen said Wednesday.

EU leaders agreed last month to loan Ukraine 90 billion euros ($105 billion) to help cover its needs in 2026 and 2027. Kyiv would only have to pay the money back once Russia ends its war and pays reparations for the damage it has inflicted over almost four years.

Britain's government is expected to approve a "mega" Chinese Embassy close to London's financial district after years of controversy and political wrangling over the potential security risks it poses to the U.K.

Lawmakers from across the spectrum have urged planning officials to reject China's application for the new embassy. Critics fear the proposed new building, on a huge site close to London's financial district and crucial data cables, will be used as a base for espionage. Others say the supersized embassy — set to be the biggest Chinese Embassy in Europe — will pose a heightened threat of surveillance and intimidation to Chinese dissidents in exile.

In Japan's ancient capital, Nara, deer moved through grass fields and shaded paths, lowering their heads toward visitors holding special crackers made just for them.

Nara this week hosted a Japan–South Korea summit, with Japanese Prime Minister Sanae Takaichi, who is from the city, welcoming South Korean President Lee Jae Myung.

Scientists on Wednesday inaugurated the first global repository of mountain ice cores, preserving the history of the Earth's atmosphere in an Antarctic vault for future generations to study as global warming melts glaciers around the world.

An ice core is something of a time capsule, containing the history of the Earth's past atmosphere in a frozen climate archive. With global glaciers melting at an unprecedented rate, scientists have raced to preserve ice cores for future study before they disappear altogether.

China's trade surplus surged to a record of almost $1.2 trillion in 2025, the government said Wednesday, as exports to other countries made up for slowing shipments to the U.S. under President Donald Trump's onslaught of higher tariffs.

China's exports rose 5.5% for the whole of last year to $3.77 trillion, customs data showed, as Chinese automakers and other manufacturers expanded into markets across the globe. Imports flatlined at $2.58 trillion. The 2024 trade surplus was over $992 billion.
