PERTH, April 2 (Xinhua) -- Malaysian Prime Minister Najib Razak is scheduled to arrive in Western Australian city of Perth on Wednesday evening to pay a two-day visit to the front line of an international joint search effort for the Malaysia Airlines flight MH370 in southern India sea which continued to be fruitless after the Boeing 777 vanished for nearly four weeks.
During the visit, at the personal invitation of his Australian counterpart, Tony Abbott, Najib will receive briefings on the search effort at the Royal Australian Air Force Base Pearce, about 38 kilometers north to downtown Perth.
According to Prime Minister Abbott's office, Najib will tour Base Pearce and personally thank the international forces taking part in the search, and he will see first-hand the dedication and skill of the international contingent that has marshaled resources for the search.
Abbott said in a press release that "we continue to hope that answers to the baffling mystery behind MH370 will be found to give some comfort to the grieving family and friends of passengers and crew."
Najib will be accompanied by Abbott and Australian minister for defense who will receive briefings from the recently formed Joint Agency Coordination Center (JACC) headed by retired Air Chief Marshal Angus Houston.
Ten aircraft and nine ships searched an area of about 237,000 square kilometers on Wednesday, about 1,500 kilometers west northwest of Perth. There were so far no sightings reported of any objects related to the missing MH370, according to Australian initiative JACC in Perth.
Weather in the search area was fair, with visibility of approximately 10 kilometers.
Royal Navy submarine HMS Tireless has arrived in the southern Indian Ocean and been tasked to assist in the search for flight MH370 as part of the international effort.
HMS Tireless, a Trafalgar Class submarine, has advanced underwater search capability, which will be a valuable contribution to the search for the missing plane, the JACC said.
Additionally, HMS Echo is in the search area to assist in efforts to locate the transponder on the black box with its advanced environmental assessment capability that will help to optimize search operations.
The Australian Transport Safety Bureau continued to refine the area where the aircraft entered the water based on continuing ground-breaking and multi-disciplinary technical analysis of satellite communication and aircraft performance, passed from the international air crash investigative team comprising analysts from Malaysia, the United States, the United Kingdom, China and Australia.
