The US and Russian presidents previously discussed Middle East tensions in an hour-long phone conversation

US President Donald Trump said on Sunday he is open to Russian President Vladimir Putin serving as a mediator in the Israel-Iran conflict. In an hour-long phone call the previous day, the two leaders focused on the Middle East crisis.

"Yeah, I would be open to it. He is ready. He called me about it," Trump responded to ABC News' Rachel Scott, when asked about Putin's potential role in brokering peace.

"We had a long talk about it. We talked about this more than his situation. This is something I believe is going to get resolved," Trump added.

After the phone call the Kremlin later said that Putin had condemned Israel's strikes on Iran and expressed concern over further escalation, while reiterating Russia's willingness to facilitate negotiations.

Putin recalled that Moscow had previously proposed concrete measures to facilitate "mutually acceptable agreements" in US-Iran nuclear negotiations before the current escalation, presidential aide Yuri Ushakov revealed.

"Russia's principled position and commitment to resolving this issue remain unchanged," Ushakov stated. "As President Putin emphasized, we will continue to act accordingly."

Despite the cancellation of Oman-mediated nuclear negotiations between Tehran and Washington following Israel's strikes, Trump maintained that discussions continued. "They'd like to make a deal. They're talking," he said, suggesting the escalation might actually accelerate diplomacy.

When asked about possible American engagement in the conflict, Trump stated: "We're not involved in it. It's possible we could get involved. But we are not at this moment involved."

The conflict in the Middle East escalated on June 12 when Israel struck Iranian nuclear sites, killing senior military officials and prompting retaliatory missile barrages from Tehran. Both sides have exchanged fire for a third straight day.
