KUALA LUMPUR, April 19 -- Malaysian acting Transport Minister Hishammudin Hussein said here on Saturday that the next two days will be "very crucial" as the search area for the missing flight MH370 has been narrowed.

The autonomous underwater vehicle Bluefin-21 will complete its scanning of the key area of the seabed in the southern Indian Ocean next week, but the search operation will continue, he told a press conference.
