Iran's navy appears to have quietly scrapped plans to make its first-ever visit to Azerbaijan.
Iranian officials announced earlier this month that a three-ship contingent from their Caspian fleet would be visiting Baku after a stop in Astrakhan for joint exercises with Russia's Caspian Flotilla. The stop in Russia seems to have gone as planned, but on Friday Iranian military officials announced that the ships had returned home to Iran, with no mention of the previous Azerbaijani plans.
"The Iranian fleet of warships comprising Joshan (Shield) and Peykan (Arrow) warships and the hi-tech Damavand destroyer which embarked on a 12-day voyage in the Caspian Sea on October 18 and after conducting joint naval drills with the Russian Navy and berthing at Russia's Astrakhan port returned home today," Navy Commander Rear Admiral Habibollah Sayyari told the Fars news agency. (It's worth noting that the tour was originally said to be 14 days.)
So what happened to Baku? Although the planned visit was reported in the Azerbaijani media at the start of the trip, there seems to have been no mention since then about the visit or that it had been canceled.
There are plenty of reasons to imagine why such a visit wouldn't take place, greatest among them being that Azerbaijan considers Iran to be its greatest threat in the Caspian. But that's not new since mid-October, so what changed since then? Given the transparency of the countries involved we're not likely to find out any time soon.
