Three pieces of wreckage linked to missing Malaysia Airlines Flight 370, nicknamed MH370, officially arrived in Malaysia this weekend for testing. A fourth was set to ship Monday, Transport Minister Liow Tiong Lai told the New Straits Times Sunday.

"The pieces will be analyzed here, and if necessary, it will be sent to Australia for further verification that they belong to the missing Malaysia Airlines MH370," he said, suggesting that the search for the missing plane shift to the African coastline. "We hope with all the support, we are able to recover more debris."

It was not immediately clear which plane remains Liow was referring to — Australian authorities have already confirmed that two pieces of Mozambique debris, one found by an American lawyer in February and one by a South African teenager in December, were "highly likely to have come from MH370," the Guardian reported.

MH370 disappeared in March 2014 en route from Kuala Lumpur to Beijing. All 239 people on board are presumed dead, and the Boeing 777 itself is thought to have crashed somewhere in the Indian Ocean. Officials have conclusively verified only one piece of debris from the plane: a flaperon wing part that washed up on Réunion Island off the coast of Madagascar last year.

But another piece of wreckage was discovered March 31 on the nearby island of Mauritius.

"For sure it looked like part of an aeroplane — it looks like it's from the inside part of it," William Auguste, the owner of the hotel whose guests found the items, told Reuters. "There was wallpaper inside of the plane. You can see this design, and part of it is still there."

Voice2370, a group of relatives of the victims, told NBC News last month it wanted the search efforts to be refocused near Mozambique and Madagascar. "We urge states with assets in the East Coast of Africa to support such an effort," it wrote in a statement. "We also seek support from naval powers to supply search assets that allow searches closer to uninhabited or swampy portions of the coast be searched effectively."

The search for the plane has swept more than 95,000 square kilometers of ocean floor without results. It will conclude if it reaches 120,000 square kilometers without finding further evidence, according to the Australian agency leading the search.
