The risk of renewed full-scale war between the US and Iran is increasing. Now according to American intelligence, Iran is in an advanced stage of preparing assassinations against American officials and diplomats. At the same time, Tehran expects a new large-scale attack by the United States and Israel. Amid the threats, Washington increased security measures and earlier removed B-1 bombers from a UK base. The Pentagon also expanded the list of possible targets for strikes against Iran to include the country's energy and key economic infrastructure.
