US Secretary of State Rex Tillerson said the United States is working with its allies and its European partners to counter Iran's destructive and destabilizing policies in the region and its support with weapons to terrorist organizations in the region.
"What worries us most is the ballistic missile programs, destabilizing Yemen and exporting weapons to terrorist organizations such as Hezbollah and Hamas foreign fighters in Iraq and Syria," Tillerson said in remarks published on the State Department website.
"Iran is only aiming to destabilize the region, and many of these conflicts are ongoing because of Iran's involvement," he said.
"Together with our partners in the region and in Europe, we want to hold Iran accountable for its actions".
"To that end, we have taken unilateral action on our own to impose sanctions on certain Iranian individuals and entities responsible for such activities while at the same time maintaining our commitments under the Comprehensive Nuclear Action Plan."
"Our European partners have the same concerns about Iranian activities. Last week, when I was in Europe, we held a meeting with our European counterparts in the Comprehensive Action Plan - the Quartet - to talk more about how we could work together to achieve a more stable situation in the Middle East, and that the Iran situation is a big dilemma that we must address together. "
He stressed that there were "weak points" in the nuclear agreement, and therefore should be reviewed.
He pointed out that America's policy towards Iran was very limited and focused only on the nuclear agreement, while the rest of the issues related to Iran were neglected.
