The Italian Navy on Thursday rescued 233 migrants from a boat in choppy waters in the Mediterranean Sea south of Sicily. One boat, with a total of 233 people, was sighted late Wednesday as it was struggling in strong winds and rough waters some 80 nautical miles from the Italian island of Lampedusa. Its passengers — most of whom come from Eritrea, Nigeria, Somalia, Pakistan, Zambia and Mali — were transferred onto the Navy’s San Marco ship and were due to arrive in the Sicilian port of Augusta, near Syracuse, later on Thursday.
