Relatives of some of the people missing after the 2014 disappearance of Malaysia Airlines flight MH370 urged Malaysia today to resume searching for the plane as they handed over what they believe are five new pieces of debris from it.

Flight MH370 was on its way from Kuala Lumpur to Beijing on March 8, 2014, with 239 people on board, when it vanished and became one of the world's greatest aviation mysteries.

The next of kin of some of those on board handed the government the five pieces of debris they said had been found by villagers in Madagascar, in three locations, one segment found as recently as August.

"The fact that debris is still washing up now means that the investigation should still be live. It shouldn’t be closed," said Grace Nathan (photo), a lawyer whose mother, Anne Daisy, was on the plane.

Malaysian and international investigators believe the jet veered thousands of miles off course before plunging into the Indian Ocean.

In July, investigators released a 495-page report, saying the plane's controls were likely deliberately manipulated to take it off course but they were not able to determine who was responsible.

More than 30 bits of suspected debris have collected from various places around the world but only three wing fragments, which washed up along the Indian Ocean coast, have been confirmed to be from MH370.

Transport Minister Anthony Loke, who met the next of kin, said the government would consider resuming a search if it were provided with credible leads.

"We are open to proposals, but we must have some credible leads before we decide," Loke said.

In May, Malaysia called off a three-month search by US firm Ocean Infinity, which spanned 112,000 sq km in the southern Indian Ocean and ended with no significant findings.

It was the second major search after Australia, China and Malaysia ended a fruitless A$200 million (US$144.80 million) search across an area of 120,000 sq km last year.
