The 190 meter long, 56969 dwt bulk freighter Arizona went aground at St. Petersburg, Russia.   The Arizona was departing the port bound for Houston with a cargo of steel when it struck bottom.   The freighter’s draft had increased unexpectedly due to ice forming on vessel’s keel.  Four tugs were attempted to refloat the vessel, but failed to do so.   No reports of injuries or pollution being released.   Divers have been requested to inspect the hull for any damage.
