Poland and about 40 of its allies on Friday denounced the intrusion of Russian drones into its airspace this week, calling on Moscow to avoid more “provocations”. Before an emergency meeting of the UN security council requested by Poland, deputy foreign minister Marcin Bosacki told reporters that Warsaw and its allies wanted to “draw the attention of the international community to yet another flagrant violation of international law and the Charter of the United Nations committed by the Russian Federation”, which had brought “the entire region closer to conflict than at any time in recent years”. The comments were from a statement signed by about 40 countries, including the 26 other members of the European Union, Ukraine, the United States, Japan and Canada. “We take this opportunity to reiterate our call on the Russian Federation to immediately cease its war of aggression against Ukraine, to renounce any further provocations, and to respect its obligations under the UN Charter,” he said. “Escalation cannot lead to peace.”

France, Germany and Denmark will contribute fighter jets and other military assets to an enhanced defence of Poland against future Russian drone incursions, Nato leaders announced at a press conference on Friday. The UK is also expected contribute to the Eastern Sentry mission, which will gradually be expanded from the Arctic in the north to the Black Sea and Mediterranean in the south to better tackle Russian drones and missiles.

The latest blow to faltering diplomacy came as Russia’s army staged major military drills with its key ally Belarus. The military drills started on Friday, and include exercises close to the border with Poland and Lithuania and in the Baltic and Barents seas. Russia’s defence ministry posted a video showing heavy military equipment – including armoured vehicles, helicopters and navy ships – taking part in the drills. Poland said it would station about 40,000 troops near the Belarus border for the duration of the drills.

Prince Harry laid a wreath at a flower and flag memorial to Ukraine’s war dead in Kyiv’s Maidan Square during a surprise visit to support the country in its fight against Russia, saying he wanted to do “everything possible” to help the thousands of military personnel who have been seriously injured in the war against Russia. During the trip to Kyiv, Harry and a team from his Invictus Games Foundation gave details of new initiatives to support the rehabilitation of the wounded, with the eventual aim of providing help to all areas of the country.

Russia said peace talks with Ukraine were on “pause” as President Volodymyr Zelenskyy warned that Vladimir Putin still wanted to capture the whole of Ukraine. “Our negotiators have the opportunity to communicate through channels. But for now, it is probably more accurate to talk about a pause” in talks, Kremlin spokesman Dmitry Peskov told reporters. Speaking at a conference in Kyiv, Zelenskyy said the west should not trust Putin. “Putin’s goal is to occupy all of Ukraine. And no matter what he tells anyone, it is clear that he has set the war machine in motion to such an extent that he simply cannot stop it unless he is forced to fundamentally change his personal goals,” he said. The Ukrainian president also called on allies to encourage China to use its leverage with Russia to stop Moscow’s offensive.

Trump told Fox television his patience was being taxed by Russia’s refusal to end its invasion. “It’s sort of running out and running out fast, but it does take two to tango,” Trump told Fox television. “It’s amazing. When Putin wants to do it, Zelensky didn’t. When Zelensky wanted to do it, Putin didn’t. Now Zelensky wants to and Putin is a question mark. We’re going to have to come down very, very strong,” he added. The Ukrainian president has long been open to efforts to meet and agree a ceasefire.
