Ukraine war: US releases last military aid for Kyiv for now
The White House has approved another tranche of US military aid to Ukraine worth some $250m (£195m).
The latest package includes air defence, artillery and small arms ammunition, and anti-tank weapons, US officials say.
But it marks the last funding available without fresh approval from Congress, where talks have stalled.
Ukraine has warned that the war effort and its public finances are at risk if further Western aid is not forthcoming.
Amid a stalled counter-offensive in the east of the country and a little-changed line of control, Ukrainian officials are facing the prospect of a slowdown in aid from allies in Washington and Europe.
Although the Ukraine war effort has broad support in the US Congress, an agreement on further arms has been stopped by Republicans who insist that tougher security measures on the US-Mexico border must be part of any military aid deal.
An emergency spending measure that would have provided $50bn for Ukraine and $14bn for Israel was defeated in the Senate earlier this month, with every Republican voting against it - along with Bernie Sanders, an independent who usually votes with Democrats but has expressed concerns about Israel's war against Hamas.
A subsequent visit by Ukrainian President Volodymyr Zelensky failed to sway lawmakers.
Wednesday's announcement will see the weapons pulled from existing Pentagon stocks, a move which does not need Congressional approval.
Secretary of State Antony Blinken said in a statement announcing the aid package that it was "imperative that Congress act swiftly, as soon as possible, to advance our national security interests by helping Ukraine defend itself and secure its future".
"Our assistance has been critical to supporting our Ukrainian partners as they defend their country and their freedom against Russia's aggression," he added.
Earlier this month a €50bn EU aid package for Ukraine was blocked by Hungary.
India targets net-zero carbon emissions by 2070, says Modi
India’s economy will become carbon neutral by the year 2070, the country’s prime minster has announced at the COP26 climate crisis summit in Glasgow. The target date is two decades beyond what scientists say is needed to avert catastrophic climate impacts. India is the last of the world’s major carbon polluters to announce a net-zero target, with China saying it would reach that goal in 2060, and the United States and the European Union aiming for 2050.
COP26: What climate summit means for one woman in Bangladesh
China's carbon emissions are vast and growing, dwarfing those of other countries. Experts agree that without big reductions in China's emissions, the world cannot win the fight against climate change. In 2020, China's President Xi Jinping said his country would aim for its emissions to reach their highest point before 2030 and for carbon neutrality before 2060. His statement has now been confirmed as China's official position ahead of the COP26 global climate summit in Glasgow. But China has not said exactly how these goals will be achieved.

Deliver on promises, developing world tells rich at climate talks
A crucial U.N. conference heard calls on its first day for the world's major economies to keep their promises of financial help to address the climate crisis, while big polluters India and Brazil made new commitments to cut emissions. World leaders, environmental experts and activists all pleaded for decisive action to halt the global warming which threatens the future of the planet at the start of the two-week COP26 summit in the Scottish city of Glasgow on Monday. The task facing negotiators was made even more daunting by the failure of the Group of 20 major industrial nations to agree ambitious new commitments at the weekend.
