A relative of a passenger onboard the missing Malaysia Airlines Flight MH370 writes a message on a whiteboard at a hotel in Beijing March 18, 2014. Malaysia's top official in charge of the search for a missing jetliner rejected criticism on Tuesday from U.S. officials that it has not been sharing as much information as it could with foreign governments. The message on the board reads, "For our families: hunger protest, give back our families, we need the truth." REUTERS/Kim Kyung-Hoon (CHINA - Tags: DISASTER TRANSPORT)
