Russia’s President Vladimir Putin and US President Donald Trump on Monday discussed the Iran war and Ukraine conflict during a “frank and constructive” telephone call, the Kremlin said.

Putin and Trump held a one-hour call in their first talks since December, and Washington sought the discussion, Putin’s diplomatic adviser Yuri Ushakov was quoted as saying by Russian news agencies.

“The accent was placed on the situation surrounding the conflict with Iran and the bilateral negotiations under way with the representatives of the United States on settling the Ukrainian question,” Ushakov said.

Ushakov said Putin called for a “quick political and diplomatic settlement” to the US-Israeli war against Iran, which has been a key ally of Russia.

The Russian leader also gave Trump “a description of the current situation on the line of contact where Russian troops are progressing with a lot of success”, he added, referring to the Ukraine war.

Putin “positively evaluated the mediation efforts undertaken” by Trump in the Ukraine conflict, the adviser said.
