Malaysian authorities on Thursday said that two objects spotted by a Australian satellite in the Indian Ocean were a "credible lead" in the search.
"We now have a credible lead," Transport minister Hishammuddin Hussein told reporters at Kuala Lumpur International Airport, said an AFP report.
This "requires us overnight to verify and corroborate it," Hishammuddin said.
There are 18 ships, 29 aircraft and six ship-borne helicopters deployed in the search for the missing plane, along two corridors stretching from the southern Indian Ocean to South and Central Asia.
"Until we are certain that we have located MH370, search and rescue operations will continue in both corridors," Hishammuddin said.
"For families around the world, the one piece of information they want most is the information we just don't have: the location of MH370," he added.
