11,000 rescued
The latest to be rescued are some of the estimated 11,000 to be saved on Monday and Tuesday this week alone.
Hundreds were found adrift in unseaworthy boats in the open sea.
29 people were reported as having suffocated in the hold of one overloaded fishing boat.
It had around 1,000 people on board and was on the brink of capsizing.
The deaths bring the total number of those who perished this week to 50.

Italian officials say three heavily-pregnant women rescued on Monday gave birth on board the coastguard vessel that was bringing them to safety.
