Germany's vice chancellor is blasting what he describes as irresponsible bickering in Chancellor Angela Merkel's conservative bloc over the migrant crisis.

Bavaria's Christian Social Union, part of Merkel's Union bloc but often an awkward ally, has criticized Merkel's approach for weeks. Leader Horst Seehofer has demanded moves by Sunday to limit the migrant influx. Merkel has argued there's no way to instantly stop the influx.

Vice Chancellor Sigmar Gabriel, a center-left Social Democrat, said the infighting "would appear bizarre in normal times." He told the Spiegel Online news portal in comments published Friday: "In view of the great challenge for our country from the high immigration of refugees, the argument ... is now threatening the government's ability to act."

Merkel, Seehofer and Gabriel are to meet Sunday.

Greek Prime Minister Alexis Tsipras has expressed "endless grief" at the new migrant tragedies in the Aegean Sea, saying they put Europe to shame.

Tsipras accused the European Union of inability to effectively address the humanitarian crisis, and said Western countries that took part in military interventions in the Middle East bear responsibility for the mass migrant flows.

Speaking in parliament Friday, Tsipras said that the Aegean is washing up "not just dead children, but the very civilization of Europe."
