>> reporter: hey, natalie , good morning. one small clue here today, authorities confirming lithium batteries being carried onboard the plane. they were being carried in regulation. perhaps that goes against speculation that they might have caused a gas or fire. again, today, the australians say it has turned up nothing leaving families desperate for news. two weeks ago, flight 370 took off from this runway. since then, relatives have clung to hopes. now another agonizing wait fearing the worst.
>> i want to know. one way or the other. i want to know.
>> phillip wood from texas was on the flight. his mother says she has heard almost nothing since then.

>> reporter: this week, another mom pleaded with reporters for information. then heartbreaking scene as she was carried away by security. now, there's a police guard on the media briefing room while relatives were taken to a two-hour meeting, but they left having been told nothing. he's decided not to leave kuala lumpur until they get some news. families with so many questions while in the indian ocean , the search continues for answers.
