Putin and Iran's president deepen defence ties with 20-year pact
Russian President Vladimir Putin and his Iranian counterpart Masoud Pezeshkian deepened military ties between their countries on Friday by signing a 20-year strategic partnership that is likely to worry the West.
Under the agreement, Russia and Iran will boost cooperation in a range of areas including their security services, military drills, warship port visits and joint officer training.
Neither will allow their territory to be used for any action that threatens the other and will provide no help to an aggressor attacking either nation, according to the text, which also said they would work together to counter military threats
