World News Today: Nobel Physics Prize, Oil Below $100 and Kharkiv Strike (6 October 2026)

From a Nobel Prize for physics to falling oil prices and fresh violence in Ukraine, here are the main international stories from Tuesday 6 October, based on reports from AP and Reuters.

The 2026 Nobel Prize in Physics went to a scientist known for hunting mysterious "ghost particles" in the Antarctic ice, according to AP. The description matches work on neutrinos, extremely light particles that rarely interact with matter and are studied with detectors buried deep in the ice. The chemistry prize announcement followed shortly after.

Energy and financial markets were in focus. Reuters reported Brent crude moving deeper below $100 a barrel on Tuesday, while an AP update put U.S. crude at about $87.60. Falling oil was one factor lifting equities: European shares extended a recovery, with the pan-European STOXX 600 up about 0.8% in morning trade and heading for a third straight daily gain.

Bond markets told a more complicated story. Analysts noted that U.S. Treasury yields have risen even as oil prices fell, pointing to heavy corporate borrowing, rising government deficits and weaker foreign demand for U.S. debt. In Europe, government bond yields had recently reached multi-decade highs on inflation and borrowing worries, and the gap between French and German 10-year yields narrowed on Tuesday as investors reassessed France's risk premium.

Ukrainian officials said a Russian attack on a residential area of Kharkiv killed six people and injured 59, Reuters reported. Kharkiv's regional governor gave the figures. Russia's war in Ukraine continues to produce regular civilian casualties in the northeast of the country.

Aid sources told Reuters that airstrikes and artillery hit Ethiopia's northern Tigray region overnight into Monday. Prime Minister Abiy Ahmed has described access to the sea as critical to Ethiopia's "civilization," language that has added to regional tensions.

Reuters reported that British National Security Adviser Jonathan Powell visited Israel last week in a failed attempt to stop a planned closure of the UK consulate in Jerusalem, citing sources. Separately, the Israeli military said two strikes it carried out in the region targeted militants.

Opposition parties in India rallied for the exit of the country's chief election commissioner. Congress president Mallikarjun Kharge called the election commission "a puppet in the hands of the government," according to Reuters. The government has not accepted such characterisations in this report, and the dispute is likely to continue in parliament.

Tens of thousands of people marched across France over conditions in schools, AP reported, adding to a run of public protests over public services.

Markets will look to Federal Reserve speakers and bond auctions for direction on interest rates. The Nobel announcements continue through the week, and diplomatic attention stays on Ukraine, Gaza and the Horn of Africa.
