Iran's neighbor would like to build a "trans-Caspian" pipeline under the sea to ship natural gas to Europe, but the legality of doing so remains murky. While some of the Caspian states have treaties among themselves, the region as a whole lacks cohesive ground rules. Turkmenistan has most recently tussled with its neighbor across the sea, Azerbaijan. On June 19, a Turkmen civilian boat investigating seismic activity on the Caspian was accosted by the Azeri Border Service. The Turkmen embassy was quick to issue a statement, saying
that it would be forced to initiate "adequate measures" if Azerbaijan continued the "provocations." Since 2008, the two countries' have been engaged in a bitter dispute over the Kapaz oil field. Above, an image of what all the fighting is about: the Caspian Sea coast from the Tukmenbashi headland, Turkmenistan.
