Frustration builds as search for plane enters fourth week

About 50 family members of the Chinese passengers on board missing Malaysia Airlines flight MH370 called for answers at a news conference in Kuala Lumpur, as the search for the aircraft comes under increasing time pressure.

After their arrival in the Malaysian capital on Sunday morning, 35 relatives, in addition to about 10 who had been there for more than two weeks, held a news conference at about 3 pm, calling for "evidence, truth and the return of family members".
