Three days later, several countries have joined forces in the search and rescue operation for the missing Boeing 777 that vanished mysteriously somewhere over South China Sea carrying 239 people in it. FBI is following its own investigation of two passengers who boarded the plane with stolen passports and have sparked terror fears.

The missing Malaysia Airlines flight MH 370 has caused terror suspect. Counter-terrorism experts and agencies have launched investigation probing involvement of terrorists' link in the mysterious disappearance of the Malaysia Airlines plane, according to Telegraph UK. Since as many as four passengers are suspected of boarding the missing flight with stolen or fake passports, terror fear cannot be ruled.

However, no evidence of terror links has emerged. Three days after the disappearance of the flight, "no electronic 'chatter' has been detected indicating any known terror group" link in disappearance of MH 370, according to NBC News.

Azharuddin Abdul Rahman, DG of Malaysia's Civil Aviation body told that they are "looking at all angles" and "possibilities."

"On the possibility of hijack, we are not ruling any possibility however it is important to state that our main concern is to focus our effort to find the missing aircraft," added Abdul Rahman as quoted by news.com.au. It is reported that until now, no terror group has also claimed the responsibility as well. NBC News revealed that only "wackos" are claiming responsibility behind the disappearance of MH 370.

According to new report by news.com.au, authorities have revealed "that five passengers checked-in to fly on missing Malaysia Airlines flight MH 370 but didn't board the plane." Report reveals that the luggage belonging to these five passengers "was taken off" the plane but it is not yet known that how is that linked to the disappearance of the Malaysia Airlines flight.
