The situation in Iran was the focus of a phone call between Turkish Foreign Minister Hakan Fidan and his Iranian counterpart, Abbas Araghchi, a source in the Turkish foreign ministry told TASS.
"The ministers discussed the recent developments in Iran," the source said.
U.S. President Donald Trump said earlier that he was seriously considering using force against Tehran. Variants of reacting to the developments in Iran, including potential strikes, are expected to be presented to him soon.
