Indonesian rescue workers were racing against the clock on Wednesday in the search for survivors from a school collapse in the province of East Java, with at least 90 students still unaccounted for, along with three confirmed dead and about 100 injured.

The Russian army's advance in Ukraine slowed again in September, especially in the Donetsk region, according to an AFP analysis of data from the US-based Institute for the Study of War (ISW).

France is probing an oil tanker suspected of being part of Russia's clandestine "shadow fleet" for "serious offenses", President Emmanuel Macron said Wednesday -- stopping short of confirming reports of a link to mysterious drone flights in Denmark.

EU chief Ursula von der Leyen Wednesday vowed Russia would not succeed in sowing "division and anxiety" in the bloc, at the start of summit talks in Denmark rattled by a spate of mysterious drone flights.

Rescuers used backhoes and sniffer dogs to look for survivors in collapsed houses and other damaged buildings in the central Philippines Wednesday, a day after an earthquake killed at least 69 people.

Plunged into a government shutdown, the U.S. is confronting a fresh cycle of uncertainty after President Donald Trump and Congress failed to strike an agreement to keep government programs and services running by Wednesday's deadline.

Roughly 750,000 federal workers are expected to be furloughed, some potentially fired by the Trump administration. Many offices will be shuttered, perhaps permanently, as Trump vows to "do things that are irreversible, that are bad" as retribution. His deportation agenda is expected to run full speed ahead, while education, environmental and other services sputter. The economic fallout is expected to ripple nationwide.

Iran said Tuesday that 120 nationals being deported from the United States under President Donald Trump's immigration crackdown, will fly home this week.
