Chinese Martyrs' Brigade group claims responsibility for flight MH370

A group that calls itself the Chinese Martyrs' Brigade has claimed responsibility for crashing Malaysia Airlines flight MH370, which has remained missing after losing contact with ground control at 1:20am on Saturday.
The previously unheard-of group sent a PDF statement to various journalists in China on March 9, saying, "You kill one of our clan, we will kill 100 of you as pay back."
The majority of Chinese media outlets have expressed skepticism over the statement or dismissed it outright, suggesting it is likely a hoax made up by opportunists looking to inflame ethnic tensions following a series of attacks by separatists in northwest China's Xinjiang Uyghur autonomous region and a mass stabbing in the Yunnan capital of Kunming this month that left at least 33 people dead.
Analysts say the credibility of the statement is dubious as the group claiming responsibility for flight MH370 did not divulge any details as to how it crashed the plane. The PDF statement was also sent via the encrypted Hushmail anonymous remailer service which cannot be replied to or easily traced. Chinese authorities have not responded to the statement or its claims.
