Chinese relatives of the missing passengers aboard Flight MH370 have travelled to Malaysia, furious at the government's handling of the search.
During a news conference they held banners saying "Hand us the murderer. Give us our relatives," and "We want evidence, truth, dignity".
They believe they are owed an apology from the prime minister for saying there is no hope of anyone surviving the crash.

Malaysia's acting Transport Minister Hishammuddin Hussein, said before the families arrived: "The hardest part of my job is to see the families."
The Beijing-bound plane disappeared on 8 March with 239 people on board, 153 of whom were Chinese.
So far there has been no confirmed sightings of any wreckage.
On Sunday, Australian officials said they had spotted four orange objects in the search area but they can't be sure they belong to the plane at the moment.
Objects spotted earlier have been discounted as fishing equipment and other flotsam.
The search is becoming increasingly frantic as the battery on the aircraft's black box recorder only has around nine days of battery left.
If it can't be located before it runs out of power the only way it could be found would be a visual sweep on the sea floor by submersibles, a process that could take years due to the depth of the ocean and inhospitable conditions.
