The number of people missing in the Italian cruise shipwreck near the coast of Tuscany rose to 29, Tgcom24 television reported citing local port authorities.
The Costa Concordia liner with over 4,200 passengers on board, ran aground off the Isola del Giglio island late Friday. Earlier reports said at least 16 people were missing.
"I have received a report from the Grosseto prefecture saying that 29 people are listed as missing - 25 passengers and four crew members," port official Marco Brusco said late Monday.
"There are, presumably, about 10 Germans and six Italians among the missing," Brusco said.
Rebello Russell Terrance, an Indian crew member on board the Italian cruise ship which ran aground in the Mediterranean Sea, is also missing and has not been traced yet, said Indian external affairs minister SM Krishna on Monday.
Tgcom24, however, reported that the fate of four French citizens and two Americans was also unknown.
The confirmed toll from the disaster rose to six Monday after rescuers discovered three more victims, including the bodies of two elderly men wearing life vests inside the vessel.
