The sources said a mission plan should be brought to the Cabinet for approval on Friday, and the necessary parliamentary vote to endorse it may be held on Monday.
“The exact number of ships and sailors is still being worked out,” said the source.
“If parliament approves, the mission might begin “by the end of August”, he said, explaining that the navy can be ready to put it in place “in a matter of hours”.
The source said Italy wants the UN agencies to bolster their presence there and also to operate migrant camps that respect human rights.
Prime Minister ,Paolo Gentiloni, met with military chiefs and ministers on Thursday to discuss “security, immigration and the Libyan situation”.
He had said on Wednesday Libya’s UN-backed government in Tripoli had invited Italian warships into its territorial waters.
Tripoli had refused access to its waters to the European Union’s anti-trafficking sea mission Sophia since 2015, hobbling efforts to stop smugglers.
As a result, some 600,000 migrants have reached Italy by sea from North Africa since 2014.
Most came through Libya, where people smugglers operate with impunity amid the turmoil that has gripped the country since Muammar Gaddafi was overthrown in 2011.
A command ship heading a flotilla of at least five smaller vessels and up to 1,000 sailors will be used in the mission, newspaper Corriere della Sera reported.
The newspaper said planes, helicopters and drones will also be used.
The rules of engagement, the area of coastline to be patrolled and the nature of cooperation with Libya’s security forces have yet to be defined, the source said.
Migrants who reach international waters are brought to Italy because Libya is not considered a safe place for refugees, and returning them there would be a violation of international non-refoulement law.
According to the UN, the Libyan coastguard returned migrants to detention centres where they are held indefinitely in “inhuman” conditions.(Reuters/NAN)
