Russia uses Iran as base to strike against Islamic State

In a move underscoring Moscowās increasingly close ties with Tehran, long-range Russian Tupolev-22M3 bombers and Sukhoi-34 fighter bombers used Iranās Hamadan air base to strike a range of targets in Syria.
It was the first time Russia has used the territory of another nation, apart from Syria itself, to launch such strikes since the Kremlin launched a bombing campaign to support Syrian president Bashar al-Assad in September last year.
