SYDNEY—Australia turned down on Sunday an offer to take 150 asylum seekers being held in an Australian-run detention center in Papua New Guinea, where U.N. officials have warned a humanitarian emergency is unfolding.
About 600 men have barricaded themselves inside the camp on remote Manus island in Papua New Guinea, defying efforts by Australia and PNG to shut it. Food, running water and medical services were cut off by Australia five days ago.
