The Italian navy said on Tuesday it had rescued nearly 600 Syrian, Palestinian and Eritrean migrants crossing the Mediterranean in two overcrowded boats, including 62 mi**rs. The Italian frigate Grecale pulled 323 Syrians and Palestinians to safety late on Monday, after helping rescue a**ther 273 migrants from Eritrea, who were taken aboard the gunboat Sfinge, the navy said in a statement. The migrants, including 103 women, were spotted by a plane patrolling the seas off Italy as part of an operation launched after two October shipwrecks in which hundreds drowned. Italy began its operation "Mare **strum" -- ("Our Sea") a Latin reference to the Mediterranean -- after more than 400 migrants from Eritrea and Syria perished in twin tragedies off Italian shores in October 2013.
