Ukrainian President Volodymyr Zelensky has condemned political violence after an apparent assassination attempt against Donald Trump, allegedly carried out by a suspect who had travelled to Ukraine to support the war effort.
"It's good that the suspect in the assassination attempt was apprehended quickly. This is our principle: the rule of law is paramount and political violence has no place anywhere in the world," Mr Zelensky said, addressing his best wishes to Mr Trump and his family.
The Kremlin, meanwhile, said that the presumed assassination attempt was a sign that the US election campaign was "intensifying".
"We can see how tense the situation is there, including between political rivals - the political fight is intensifying," Kremlin spokesman Dmitry Peskov said.
"We are watching it closely, but we have never interfered in this in any way and we are not interfering now," he said.
Mr Peskov said that the Ukrainian links of the alleged shooter showed that "playing with fire" had consequences.
CNN, Fox News and the New York Times identified the suspect as Ryan Wesley Routh, 58, of Hawaii, citing unidentified police officials.
Asked about what the FBI called an assassination attempt on Mr Trump, Mr Peskov said that Moscow was following the tense situation in the United States, and said that Russia was not interfering in the presidential election.
"It is not us who should be thinking, it is the US intelligence services who should be thinking. In any case, playing with fire has its consequences," he said.
The comment was a clear reference to the US' support of Ukraine against Russia.
Starmer 'very worried'
British Prime Minister Keir Starmer said he was "very worried" about what he said looked like an assassination attempt on Mr Trump.
Mr Starmer told broadcasters in Rome: "I was very worried by the news about this attempt. Looks like an assassination attempt, very worried about it."
He added: "Obviously, there's now an investigation going on so I won’t say much more about the details, but I think it is really important that we’re all very, very clear that violence has no part to play at all in any political process.
"So, deeply troubled. Let the investigation take its place. But absolute clarity: violence, no place in political discussion at all, anywhere."
