ROME (Reuters) - Migrants rescued from two boats in the Mediterranean this week told humanitarian workers in Italy that they saw another vessel carrying some 400 migrants sink, Save the Children said on Saturday.

Three vessels carrying migrants already are confirmed to have sunk or capsized this week. More than 60 bodies are said to have been recovered, including those of three infants, and hundreds are believed to be missing.
