Updated at 5:55 p.m. ET -- Divers found a total of five bodies in the wreckage of the Costa Concordia on Thursday.
Two more bodies were found following the discovery of three earlier in the day, NBC News has learned. Officials have not said when the bodies will be identified, saying, "it will take time."
Thursday's discoveries bring the total number of bodies recovered up to 30. Two others remain missing and are presumed dead.
The luxury cruise liner capsized after hitting rocks on Jan. 13 near the island of Giglio off Italy's Tuscan Coast.
Even before the latest bodies were found, eight discovered in recent weeks were awaiting official identification. The remains were badly decomposed after weeks in the water, and forensic authorities have used DNA sampling to try to identify them.
Among those listed as missing or unidentified are a crew member from India and several passengers, including an elderly U.S. couple, and others from Italy and Germany.
Francesco Schettino, the ship's captain, was arrested a day after the accident and accused of manslaughter and abandoning the 114,000-ton Costa Concordia before all the 4,200 passengers and crew were evacuated.
He admitted to prosecutors that he sailed too close to the island and was released from prison and placed under house arrest on Jan. 17.
