Here is Malaysia's Acting Transport Minister Hussein Hishammuddin's statement in full:
During the last 24 hours, the Prime Minister has spoken to the Prime Minister of Australia and the Premier of China. Malaysia's Ministry of Foreign Affairs has sent diplomatic notes to all countries involved in the search and rescue operation.
This includes two groups: first, countries in the search corridors; and second, countries from which we are seeking assistance and expertise.
For countries in the search corridors, we are requesting radar and satellite information, as well as specific assets for the search and rescue operation. We are asking them to share their land, sea and aerial search and rescue action plans with the Rescue Co-ordination Centre here in Malaysia, so that we can co-ordinate the search effort. We have asked for regular updates, including daily reports on both search activities, and details of any information required from Malaysia.
We are not at liberty to reveal information from specific countries. As the co-ordinating authority we are gathering all information as part of the on-going search and rescue operation. Over the past 48 hours, Malaysia has been working on the diplomatic, technical and logistical requirements of the search for MH370. The number of countries involved in the search and rescue operation has increased to 26.
Malaysia continues to lead the overall co-ordination of the search effort. The southern corridor has been divided into two sections, according to International Civil Aviation Organisation (ICAO) demarcations.
These demarcations were agreed by the ICAO - of which Malaysia is a council member - before MH370 went missing. Australia and Indonesia have agreed to lead search and rescue operations in their respective regions as demarcated by the ICAO.
Today, I can confirm that search and rescue operations in the northern and southern corridors have already begun.
Countries including Malaysia, Australia, China, Indonesia and Kazakhstan have already initiated search and rescue operations.
The Royal Malaysian Air Force and the Royal Malaysian Navy have deployed assets to the southern corridor. Two Malaysian ships have been deployed: the offshore patrol vessels KD Kelantan and KD Selangor. This deployment also includes a Super Lynx helicopter, which can operate from either ship.
