President Joe Biden's administration has allowed Ukraine to use U.S.-made weapons to strike deep into Russia, two U.S. officials and a source familiar with the decision said on Sunday, in a significant reversal of Washington's policy in the Ukraine-Russia conflict, Reuters reported.

Ukraine plans to conduct its first long-range attacks in the coming days, the sources said, without revealing details due to operational security concerns.

The move comes two months before President-elect Donald Trump takes office on Jan. 20 and follows months of pleas by Ukrainian President Volodymyr Zelenskiy to allow Ukraine's military to use U.S. weapons to hit Russian military targets far from its border.

The change comes largely in response to Russia's deployment of North Korean ground troops to supplement its own forces, a development that has caused alarm in Washington and Kyiv, a U.S. official and a source familiar with the decision said.

Zelenskiy said in his evening address that the missiles would "speak for themselves."

"Today, many in the media are saying that we have received permission to take appropriate actions," he said. "But strikes are not made with words. Such things are not announced."

The White House and U.S. State Department declined to comment.

There was no immediate response from the Kremlin, which has warned that it would see a move to loosen the limits on Ukraine's use of U.S. weapons as a major escalation, read the report.

Vladimir Dzhabarov, first deputy head of the Russian upper house's international affairs committee, said Washington's decision to let Kyiv strike deep into Russia could lead to "World War Three".

"The West has decided on such a level of escalation that it could end with the Ukrainian statehood in complete ruins by morning," Andrei Klishas, a senior member of the Federation Council, Russia's upper chamber of parliament, said on the Telegram messaging app.

Ukraine's first deep strikes are likely to be carried out using ATACMS rockets, which have a range of up to 190 miles (306 km), according to the sources.

While some U.S. officials have expressed skepticism that allowing long-range strikes will change the war's overall trajectory, the decision could help Ukraine at a moment when Russian forces are making gains and possibly put Kyiv in a better negotiating position when and if ceasefire talks happen.

It is not clear if Trump will reverse Biden's decision when he takes office. Trump has long criticized the scale of U.S. financial and military aid to Ukraine and has vowed to end the war quickly, without explaining how, Reuters reported.

A Trump spokesperson did not immediately respond to a request for comment. But one of Trump's closest foreign policy advisers, Richard Grenell, criticized the decision.

"Escalating the wars before he leaves office," Grenell said, in an X post responding to the news.

Some congressional Republicans had urged Biden to loosen the rules on how Ukraine can use U.S.-provided weapons.

Since Trump's Nov. 5 victory, senior Biden administration officials have repeatedly said they would use the remaining time to ensure Ukraine can fight effectively next year or negotiate peace with Russia from a "position of strength".

The U.S. believes more than 10,000 North Korean soldiers have been sent to eastern Russia and that most of them have moved to the Kursk region and have begun to engage in combat operations.

Russia is advancing at its fastest rate since 2022 despite taking heavy losses, and Ukraine said it had clashed with some of those North Korean troops deployed to Kursk.

Stretched by personnel shortages, Ukrainian forces have lost some of the ground they captured in an August incursion into Kursk that Zelenskiy said could serve as a bargaining chip.

"Removing targeting restrictions will allow the Ukrainians to stop fighting with one hand tied behind their back," Alex Plitsas, senior non-resident fellow at the Atlantic Council, said.

"However, like everything else, I believe history will say the decision came way too late. Just like the ATACMS, HIMARS, Bradley Fighting Vehicles, Abrams tanks and F-16. They were all needed much sooner," he added.

Despite Zelenskiy's pleas, the White House had been reluctant to allow U.S.-supplied weapons to be used to strike targets deep inside Russia for fear this could ratchet up the conflict.

Republican U.S. Representative Mike Turner, who chairs the House Intelligence Committee, said in a statement that Biden’s decision was long overdue and that there were still too many restrictions on Ukraine, Reuters reported.

But he added: “This first step will put pressure on Vladimir Putin as President-elect Trump returns to the White House and works to end this war.”

Kyiv's other allies have been supplying weapons but with restrictions on how and when they can be used inside Russia, out of concern such strikes could prompt retaliation that draws NATO countries into the war or provokes a nuclear conflict.

Poland's foreign minister, Radoslaw Sikorski, also called the move a response to North Korea's involvement.

"President Biden responded to the entry of North Korean troops into the war and the massive Russian missile strike in a language that V. Putin understands - by removing restrictions on Ukraine's use of Western missiles," Sikorski said on X.

President Volodymyr Zelenskiy has said Ukraine must do all it can to ensure the war with Russia ends next year through diplomacy.

In a radio interview aired on Saturday, Zelenskiy conceded that the battlefield situation in eastern Ukraine was difficult and Russia was making advances. He said his Russian counterpart Vladimir Putin was not interested in agreeing to a peace deal.

Zelenskiy said U.S. legislation prevented him from meeting President-elect Donald Trump before his inauguration next January. The Ukrainian leader said he would only talk with Trump himself rather than any emissary or advisor.

"I, as the president of Ukraine, will only take seriously a conversation with the president of the United States of America, with all due respect to any entourage, to any people."

"From our side, we must do everything so that this war ends next year, ends through diplomatic means," Zelenskiy said.

Sri Lankans handed Anura Kumara Dissanayake a thumping win in a snap general election, giving its new leftist president greater legislative power to pursue policies to alleviate poverty and fight graft as the country recovers from a financial meltdown.

Dissanayake, a political outsider in a country dominated by family parties for decades, comfortably won the island’s presidential election in September, Reuters reported.

But his Marxist-leaning coalition, the National People’s Power (NPP), had just three of parliament’s 225 seats before Thursday’s election, prompting him to dissolve it and seek a fresh mandate.

The NPP won 107 seats, receiving almost 62% or 6.8 million votes in Thursday’s election, putting them past the majority mark in the parliament, latest results on the Election Commission of Sri Lanka’s website showed. A two-third majority appeared within reach of the coalition.

Voters directly elect 196 members to parliament from 22 constituencies under a proportional representation system. The remaining 29 seats will be allocated according to the island-wide proportional vote obtained by each party.

“We see this as a critical turning point for Sri Lanka. We expect a mandate to form a strong parliament, and we are confident the people will give us this mandate,” Dissanayake said after casting his vote on Thursday.

“There is a change in Sri Lanka’s political culture that started in September, which must continue.”

Celebrations were largely muted, with the exception of a few NPP loyalists who lit fireworks in the outskirts of the capital, Colombo.

Just over 17 million Sri Lankans were eligible to elect lawmakers for a five-year term. A record 690 political parties and independent groups were contesting across 22 electoral districts.

Samagi Jana Balawegaya party of opposition leader Sajith Premadasa, the main challenger to Dissanayake’s coalition, won 28 seats and about 18% of the votes polled. The New Democratic Front, backed by previous President Ranil Wickremesinghe, won just three seats.

TENTATIVE ECONOMIC RECOVERY

Sri Lanka typically backs the president’s party in general elections, especially if voting is held soon after a presidential vote.

The president wields executive power but Dissanayake still requires a parliamentary majority to appoint a fully-fledged cabinet and deliver on key promises to cut taxes, support local businesses, and fight poverty.

He also has plans to abolish Sri Lanka’s contentious executive presidency but requires a two-third majority in parliament to implement it.

A nation of 22 million, Sri Lanka was crushed by a 2022 economic crisis triggered by a severe shortage of foreign currency that pushed it into a sovereign default and caused its economy to shrink by 7.3% in 2022 and 2.3% last year.

Boosted by a $2.9 billion bailout programme from the International Monetary Fund (IMF), the economy has begun a tentative recovery, but the high cost of living is still a critical issue for many, especially the poor.

Dissanayake also aims to tweak targets set by the IMF to rein in income tax and free up funds to invest in welfare for the millions hit hardest by the crisis.

But investors worry his desire to revisit the terms of the IMF bailout could delay future disbursements, making it harder for Sri Lanka to hit a key primary surplus target of 2.3% of GDP in 2025 set by the IMF.
