The bodies of two women were recovered from the ship's internet café, according to a national civil protection agency official. A body was pulled from the cruise liner Sunday, bringing the number of confirmed dead to 15.
Seventeen people are still missing, but that number could increase because it appears that unregistered guests were on board at the time of the accident.
The capsized Costa Concordia was carrying 4,200 people when it rammed a reef on the island of Giglio and sliced open its hull on Jan. 13.
Divers continued search efforts for the missing people Monday, even while crews pumped fuel from the ship.
Crews determined the ship was secure enough for both actions to happen at the same time.
Salvage teams blew new holes to get access to different parts of the ship.
Many locals have been anxious to begin the fuel pumping process, fearing the 500,000 gallons of fuel aboard could start to leak.
