This is getting very little coverage so far, but both AP and Reuters are reporting that Iran fired on, then boarded, a Romanian oil rig off the coast of Iran. GSP, the Romanian company that owns the rig, has since been unable to contact anyone there.
Is this simply a case of Iran's military exercises getting a little too rambunctious, or the opening phase of something bigger?
