Iran accuses U.S. of provoking Middle East 'crises'

Tehran accused Washington of provoking tensions in the Middle East, a day after US President Joe Biden ended a tour to Iran's rival Saudi Arabia and arch-foe Israel.

Washington "has once again resorted to the failed policy of Iran-phobia, trying to create tensions and crises in the region," Iran's foreign ministry spokesman Nasser Kanani said in a statement.

The comments come after Biden on Saturday vowed that the United States would not "tolerate efforts by any country to dominate another in the region through military buildups, incursions, and/or threats", in a transparent reference to Iran.

"These false allegations are in line with Washington's seditious policy... in the region," Kanani said, adding the pact was a "great sign of the deception and hypocrisy" of the United States.
