Iran's religious leader Mojtaba Hamaney declared that US President Donald Trump's signature is "completely worthless and devoid of credibility." This statement came in response to Washington's violation of a memorandum of understanding signed by the presidents of the two countries.
In a written statement, Hamaney pointed to the mutual attacks that occurred after the ceasefire agreement between Washington and Tehran collapsed last week. The statement emphasized that US violations have been repeated.
The statement, which said that the Iranian nation and the "resistance front" would teach the US "unforgettable lessons," drew attention to the tension in the region. With the collapse of the ceasefire, there are concerns that a full-scale war could break out again between the parties.
