"The US approaches caused the previous round of negotiations, despite progress, to fail to reach its goals because of the excessive demands," said Iran's Foreign Minister Abbas Araghchi.

"The US approaches caused the previous round of negotiations, despite progress, to fail to reach its goals because of the excessive demands," said Iran's Foreign Minister Abbas Araghchi.

Foreign Minister Abbas Araghchi is set to discuss the war in Iran with his Russian counterpart Sergey Lavrov and President Vladimir Putin later on Monday.

Iran's top Foreign Minister Abbas Araghchi blamed Washington on Monday for the failure of Middle East peace talks as he met with Russian President Vladimir Putin in St. Petersburg. Putin, meanwhile, promised Araghchi Moscow's support in bringing the war to a close.

Iranian Foreign Minister Abbas Araghchi arrived in Russia on Monday for talks with President Vladimir Putin, as Tehran continues diplomatic efforts across the region while negotiations with the United States remain effectively frozen. His trip to Moscow followed a busy diplomatic weekend that included visits to Pakistan and Oman, both of which have been involved as intermediaries in attempts to reduce tensions and reopen indirect channels between Tehran and Washington.

President Donald Trump said on Sunday Iran could telephone if it wants to negotiate an end to their two-month war and stressed it can never have a nuclear weapon.

Iranian Foreign Minister Abbas Araghchi met Russian President Vladimir Putin in St. Petersburg on April 27, with both sides highlighting what they described as a growing strategic partnership between Moscow and Tehran.
