Australian authorities said Thursday they had found “credible” evidence in satellite imagery of what may be debris from the Malaysia Airlines plane that has been missing for almost two weeks.

Australian Prime Minister Tony Abbott told Parliament on earlier Thursday that the evidence was “credible,” while also cautioning that “it may turn out that they are not related to the search.”The debris was spotted in the Indian Ocean near Australia, and while authorities cautioned it could turn out to be another dead end, it was called the “best lead” yet in what has mushroomed into a massive international search for a 777 that vanished with 239 people aboard. Australian aircraft arrived in the area about 1,500 miles southwest of the country but were unable to immediately find the objects spotted by satellite because “cloud & rain limited visibility,” the Australian Maritime Safety Authority (AMSA) said. Other aircraft from the United States and New Zealand were en route to aid the search operation. Relatives of the passengers on the missing jet, who have grown increasingly anguished over the lack of answers provided by the search, gathered at a hotel in Beijing to await news. As night fell in the Indian Ocean, Australian officials said they were calling off their search for the day and would resume on Friday morning.The debris was spotted in the Indian Ocean near Australia, and while authorities cautioned it could turn out to be another dead end, it was called the “best lead” yet in what has mushroomed into a massive international search for a 777 that vanished with 239 people aboard.
