NATO has warned that U.S. concern over Iranian terror activity should not spell the end of a fragile nuclear deal.
In 2015, a group of countries that included the U.S., agreed to ease sanctions on Iran if the country agreed to curtail development of its nuclear program.
Since coming to power in January, U.S. President Donald Trump has said he could cancel American participation in the agreement "at any time." Trump is concerned that Tehran is continuing to funnel funds to terrorist groups.
Speaking at the close of a two-day meeting of foreign ministers in Brussels, Belgium, on Wednesday, NATO Secretary-General Jens Stoltenberg agreed that Iran's connections to groups such as Hezbollah remained an issue.
But Stoltenberg called for the two issues of nuclear compliance and state–sponsored terrorism to be considered separately.
