New Delhi, July 4 -- US President Donald Trump on Friday expressed his 'disappointment' with Russian counterpart Vladimir Putin after their phone call over the ongoing Russia-Ukraine war.

Trump said that it does not appear that Putin is looking to stop Russia's war against Ukraine, according to a Reuters report. After speaking to Putin on Thursday, Trump plans to speak to Ukraine President Volodymyr Zelenskiy on Friday, he said in remarks to reporters on his return to Washington from a trip to Iowa.

"I'm very disappointed with the conversation I had today with President Putin, because I don't think he's there, and I'm very disappointed," Trump said.

"I'm just saying I don't think he's looking to stop, and that's too bad."
