Rescue teams on Sunday were trying to recover the bodies of three people believed missing from a Tunisian charter plane that crash landed in the sea off Sicily on Saturday.
Thirteen bodies had been recovered by Sunday afternoon. Teams were searching by air and sea for the bodies of two or three people.
One official said recovering the bodies might be difficult because they could be trapped inside part of the plane that was still submerged. The tail and the nose sank after impact.
Of the 23 survivors, 16 were treated at the Civic Hospital, but none was in a life-threatening condition, said Dr. Mario Re, head of the intensive care unit.
Gaspare Prestifilippo, division chief at the Palermo port, said emergency crews have not yet recovered the flight data recorder.
The Tuninter ATR-72 was carrying 34 passengers and five crew members when it went down in an emergency crash landing on Saturday, 16 kilometres off Sicily's Cape Gallo.
The pilot contacted aviation officials at 3:24 pm (1324GMT), reporting engine trouble and asked to make an emergency landing in Palermo.
At 3:40 pm (1340GMT) he said he was ditching the plane in the sea because he could not reach the airstrip, Tuninter director Tlili Mohamed Ali said in Tunis.
The flight had departed from Bari, Italy, for the Tunisian resort of Djerba, popular with Italian vacationers.
