EU foreign affairs chief Federica Mogherini told European nations yesterday they had "no more excuses" not to act on the migrant crisis as a boat with 300 people aboard issued a distress call from the Mediterranean. A day after a fishing boat crammed with migrants capsized off Libya with the loss of hundreds of lives, EU foreign and interior ministers met in Luxembourg to discuss the flood of people desperately trying to reach Europe.More than 700 people are feared dead in Sunday's disaster, with some survivors suggesting nearly 1000 could have been on board.As the search for victims continued, the International Organisation for Migration said it had received a distress call from another boat in the Mediterranean."The caller said that there are over 300 people on his boat and it is already sinking [and] he has already reported fatalities, 20 at least," the organisation's Federico Soda wrote in an e-mail.The European Union should take a "more sophisticated, more courageous and less callous approach" to migrants who often die trying to reach the EU in boats that are not seaworthy, UN human rights chief Zeid Ra'ad Al Hussein said."Europe is turning its back on some of the most vulnerable migrants in the world and risks turning the Mediterranean into a vast cemetery," he said.Zeid described EU policy as "short-sighted, short-term political reactions pandering to the xenophobic populist movements".Arriving at the talks in Luxembourg, Mogherini said the 28-nation EU had "no more excuses" now not to come up with a common response to the migrant tide."We need immediate action from the EU and the member states," she said.EU president Donald Tusk said he would host an emergency summit on the crisis on Thursday.Europe's southern shores have been swamped over the past two weeks with migrants fleeing war and hardship, mostly via Libya.In another tragedy police in Greece reported three people killed in the sinking of a boat off the island of Rhodes. Ninety-three people were rescued.The sail boat ran aground on a crossing from Turkey.Meanwhile, Italian and Maltese navy boats continued to scour the water for the victims of Sunday's disaster, which brings to an estimated 1600 the number of migrants who have drowned in the Mediterranean this year.About 11000 migrants have been rescued since the middle of last week alone and current trends suggest last year's total of 170000 landing in Italy is likely to be exceeded this year. ..
