Sergiu Medar, a national security adviser to Romanian President Traian Basescu, said the seizure resulted from a commercial dispute Iran is treating "in an extreme way." He gave no details.
Romania's Foreign Ministry called on Iranian authorities to immediately free Romanian crew members being held by the troops who took over the rig. The rig operator said seven Indian crew members had been released but 20 Romanians were still detained.
The Iranians first fired into the air and then fired at the Orizont rig, said GSP spokesman Radu Petrescu. Half an hour later, troops from the ship boarded and occupied the rig and the company lost contact with the 26 crew members shortly afterward. ... GSP, also known as the Oil Services Group, is a private Romanian company established in 2004 which operates six offshore rigs that it bought from Romania's largest oil company, Petrom.
Two of its rigs are operating near the Iranian coast in the Persian Gulf as part of a deal signed between Petrom, GSP and Dubai-based Oriental Oil Co.
It sounds like Iran wants to cancel the original grant of oil rights?
