Ukraine's Western backers on Saturday urged allies to provide Ukraine with all necessary support required to beat Russia, with NATO chief Jens Stoltenberg warning of the risks of victory for Moscow, ahead of the anniversary of the war's outbreak, reported news agency AFP.


World leaders have gathered at the Munich Security Conference with conflict between Ukraine and Russia still continuing almost a year after Moscow invaded Ukraine, upending the global security landscape.


Dozens of senior figures including US Vice President Kamala Harris, US Secretary of State Antony Blinken, and China's top diplomat Wang Yi are attending the conference, reported news agency AFP.


Billions of dollars of armaments have been sent to Kyiv, from artillery to air defence systems, by its allies led by the United States. But the Zelensky government says the help is not enough and the country needs more to launch a successful counter-offensive.


On the second day of the Conference, NATO Secretary General Jens Stoltenberg called for allies to step up military support for Kyiv, and said that it is the only way to counter Moscow.


"We must give Ukraine what they need to win and prevail as a sovereign, independent nation in Europe," Stoltenberg was quoted as saying by AFP.


"The biggest risk of all is if Putin wins. If Putin wins in Ukraine, the message to him and other authoritarian leaders will be that they can use force to get what they want," he added.


European Union chief Ursula von der Leyen also called for bolstered military support in areas such as ammunition supplies.


"We have to double down and we have to continue the really massive support that is necessary," she said, as reported by AFP


Ukrainian President Volodymyr Zelensky opened the meet on Friday through video conferencing and urged allies to speed up their efforts in providing more support to Kyiv.


Zelensky has recently stepped up calls for Western backers to give it combat jets, although its allies have downplayed the prospect of that happening any time soon, reported AFP.
