Acting Transport Minister Datuk Seri Hishammuddin Tun Hussein today advised family members of passengers on board a missing MAS flight to stay calm and not to heed speculation.
He said they should get information only from validated sources.
"I'm making my way to the flight management building (in Sepang) from Janda Baik (Pahang) to get updates and details from the agencies involved. In the mean time, don't speculate," he tweeted.
MAS Group chief executive officer Ahmad Jauhari Yahya has confirmed that the Kuala Lumpur-Beijing bound Flight MH370, carrying 227 passengers and 12 crew, went missing somewhere between Malaysian and Vietnamese airspace over the South China Sea at 2.40 am.
