Iran and Russia are getting closer as they carry out joint naval exercises in the Caspian sea.
Both countries say the maneuvers are aimed at improving security in the Caspian sea region.
Ownership of some of the Caspian sea is still under dispute after the fall of the Soviet Union.
Iran is one of the countries that has yet to settle how much of the Caspian sea is their territory - but the country maintains that this activity is part of international military obligations and does not have ulterior motives.
Russia and Iran have enjoyed close ties for a number of years. Russia has been helping to build Iran's controversial nuclear reactor in Bushehr and has agreed to supply it with fuel when it is operational.
Iran is one of Russia's biggest military customers and has plans to update its airforce with Russian MIG fighter jets.
How strong are these growing ties and, with Tehran coming under increasing pressure over its nuclear activities, just how does Washington view this budding alliance?
