Iran's foreign minister on Sunday rejected Vice President Pence's criticism of the Iranian government, decrying the U.S. as the "single biggest source of destabilization" in the Middle East.

“The U.S. claims ... that it is Iran which is interfering in the region, but has it ever been asked whose region?” Mohammad Javad Zarif said at a gathering of world leaders and defense officials in Munich, according to The Associated Press.

“Just glimpse at a map for a second — the U.S. military has traveled 10,000 kilometers to dot all our borders with its bases," he added.

"There is a joke that it is Iran’s fault that it put itself in the middle of all [the] U.S. bases.”

The AP noted that Zarif accused the U.S. of pushing for regime change in Iran, something Trump administration officials have said is not the case.

Zarif's comments came one day after Pence at the Munich security conference urged European allies to pull out of the 2015 Iran nuclear deal, which the U.S. withdrew from last year. The Trump administration has hammered Tehran with sanctions in the time since.

The vice president argued that France, Germany, the United Kingdom and the European Union had to join the U.S. in order to place additional pressure on Iran. Those European signatories, along with Russia, China and Iran, have remained committed to the Obama-era pact despite the U.S. withdrawal.

The AP reported that Zarif told attendees in Munich that signatories must supplement the INSTEX system, which was set up last month by France, Germany and Britain to allow businesses to avoid financial transactions with Iran and subsequent U.S. sanctions, with additional action.

“Many around the world, particularly on this continent, speak eloquently about multilateralism, but they also need to walk the walk,” Zarif said, according to the news service. “INSTEX falls short of the commitments by [European countries] to save the nuclear deal. Europe needs to be willing to get wet if it wants to swim against a dangerous tide of U.S. unilateralism.”
