African and Asian migrants have continued to flee the fighting in western Libya.
Nearly 1,200 people boarded a Greek-flagged ship in Misrata for the rebel stronghold of Benghazi, according to the International Organisation for Migration.
The aid agency said many of them needed medical treatment.
Earlier on Friday, around 1,200 people arrived in the Egyptian port of Alexandria onboard a Turkish vessel.
The most intense fighting has been centred around Misrata.
Colonel Muammar Gaddafi’s forces have been battling to reclaim control of Libya’s third-biggest city for the past six weeks.
Residents have been quoted as saying Gaddafi’s men fired as many as one hundred rockets on Misrata during Friday.
They said scores had been killed and several more have been injured, the majority of them women and the elderly.
It has left hospital staff struggling to cope with the influx of patients, although additional medical supplies are expected to be shipped in soon by the Red Cross.
Reports of casualties and deaths in western Libya are difficult to independently verify as the movements of foreign journalists in that part of the country have been heavily restricted.
