About 50 relatives of Chinese passengers from the missing Malaysia Airlines plane are continuing a sit-in protest outside the Malaysian Embassy in Beijing, after officials failed to show up to update them on the search.

The airline says relatives earlier held ten of its staff members for nearly 11 hours inside a hotel ballroom where family members were being briefed.

It says the families insisted they wait there while family members went to the embassy to try to get a Malaysian official to attend the meeting.
