Iran on Friday warned the United States against violating their bilateral memorandum of understanding, saying any breach would be met with a response.
According to Iran's Press TV, acting Defense Minister Majid Ibn Reza said during a telephone conversation with his Turkish counterpart Yasar Guler that Tehran agreed to the U.S.-Iran ceasefire under the memorandum of understanding in order to help restore stability to the region and at the request of friendly and neighboring countries.
But he made it clear that Iran has zero trust in the United States, pointing to Washington's long record of breaking its promises.
The acting defense minister said that the Armed Forces of Iran remain on full alert, and any violation of the agreement will be met with a proportionate response.
He also said foreign troops in the region do not bring security - they only increase distrust, uncertainty and insecurity.
In addition, Iran's Islamic Revolution Guard Corps warned in a statement on Friday that any miscalculation by the enemy would be met with a more decisive and devastating response than ever before.
