PERTH, Australia — A Chinese aircraft flying over the search zone for Malaysia Airlines Flight 370 on Saturday spotted several objects floating in the sea, including two bearing colors of the missing plane, but it was not immediately clear whether they were related to the investigation, officials said.

A Chinese Ilyushin IL-76 spotted three floating objects, China’s official Xinhua News Agency said, a day after several planes and ships combing the newly targeted area closer to mainland Australia saw several other objects.

Malaysian Defense Minister Hishammuddin Hussein told reporters near Kuala Lumpur after meeting several families of passengers on the plane that there was no new information on the objects spotted Friday, which could just be just sea trash or could be from the jetliner, which went missing three weeks ago.

Relatives and friends of the passengers said they were tortured by the uncertainty over the fate of their loved ones, as they wait for hard evidence that the plane had crashed.

Flight 370 disappeared March 8 while bound from Kuala Lumpur to Beijing.
