China, France, Russia, Britain, the United States, Germany and Iran should take part in the video summit, the Kremlin chief said.

"It's an urgent issue," Putin said in a statement released by the Kremlin.

"Discussions at the UN Security Council over the Iranian issue are becoming increasingly tense," Putin said, adding that Moscow's ally Iran was a target of "groundless accusations".

"The goal is to put together a blueprint that would allow to avoid confrontation, an escalation in tensions at the UN Security Council."

He added that the leaders should also agree on ways to ensure security and trust in the Gulf region.

Tensions over Iran have escalated since 2018 when President Donald Trump withdrew the United States from a multinational accord that froze Iran's nuclear programme and reimposed crippling sanctions on its economy.

Last week US Secretary of State Mike Pompeo said Washington would submit a UN Security Council resolution to extend an arms embargo on Iran despite opposition from Russia and China.
