Donald Trump news: US President attacks Vladimir Putin again as Russia offers Ukraine a new date for peace talks

US President Donald Trump has again expressed frustration with Russian President Vladimir Putin over the intensifying Ukraine conflict, a day after warning that Mr Putin was “playing with fire” by resisting ceasefire talks while escalating drone and missile attacks.

But Mr Trump also told reporters in the Oval Office on Wednesday that he was not yet prepared to impose new sanctions on Russia because he did not want the penalties to scuttle a potential peace deal.

Russia has proposed holding the next round of direct talks with Ukraine on June 2 in Istanbul, Russian Foreign Minister Sergei Lavrov said, also on Wednesday. There was no immediate response from Kyiv.

The public squabble between the US and Russia unfolded as the three-year-old war heats up, with swarms of drones launched by both Russia and Ukraine and Russian troops advancing at key points along the front.

Delegates from Russia and Ukraine met earlier this month in Istanbul under pressure from Mr Trump to end the bloodiest conflict in Europe since World War Two, but the talks failed to yield the ceasefire that Kyiv and its Western allies have pushed for. Moscow said certain conditions needed to be met before a ceasefire agreement.

Asked whether the Russian leader might be intentionally delaying negotiations, Mr Trump said, “We’re going to find out whether or not he’s tapping us along or not, and if he is, we’ll respond a little differently.”

After speaking to Mr Trump on May 19, Mr Putin said he had agreed to work with Ukraine on a memorandum which would set out the contours of a peace accord including the timing of a ceasefire.

Mr Putin’s demands for ending the war include a written pledge from Western leaders that NATO will not expand eastward to former Soviet republics such as Ukraine and Georgia and the lifting of some sanctions on Russia, according to Russian sources with knowledge of the negotiations.

In a post on Truth Social on Tuesday, Mr Trump had warned Mr Putin that he was “playing with fire” and that “really bad” things would have happened to Russia already if not for Mr Trump himself.

Mr Putin’s foreign policy aide, Yuri Ushakov, told a state TV reporter that Mr Trump’s remark suggested he is not well-briefed on the realities of the war.

Russia said on Wednesday it had downed 296 Ukrainian drones over 13 regions overnight, while Ukraine’s military said it had struck several Russian weapon production sites.

Ukraine said Russia had launched 88 drones and five ballistic missiles.

After Russia said in late April it had ejected Ukrainian forces from the western Kursk region, Moscow’s forces have pushed over the border into the neighbouring Sumy region of northeastern Ukraine and taken several villages there.

Ukrainian President Volodymyr Zelensky said that Russia has gathered 50,000 troops near the northern Sumy region, but added that Kyiv had taken steps to prevent Moscow from conducting a large-scale offensive there.

Speaking in Berlin during a visit by Mr Zelensky, German Chancellor Friedrich Merz said that Germany and Ukraine will develop the joint production of long-range missiles, a move the Kremlin said was irresponsible and amounted to stoking the war.

Russian Defence Minister Andrei Belousov said that the US-led NATO military alliance was using the Ukrainian crisis to build up its presence across eastern Europe and the Baltic but that Russia was advancing along the entire front in Ukraine.
