KUALA LUMPUR: Samples taken from an oil slick off Malaysia are not from a missing jet based on results of a chemistry lab analysis, an official said Monday.
Flight MH370 went missing over waters between Malaysia and Vietnam en route from Kuala Lumpur to Beijing early Saturday.
No confirmed evidence of the plane's fate has yet been found despite a massive search, leaving authorities stumped and anguished family members demanding answers.
Malaysian authorities had collected oil samples from a slick about 185 kilometres (115 miles) north off the country's east coast state of Kelantan and sent it for analysis in a laboratory in the capital Kuala Lumpur.
But the results came back negative for jet fuel.
"The oil is not used for aircraft," Maritime Enforcement Agency spokeswoman Faridah Shuib told AFP, adding it was a type used by ships.
The slick, from which the samples were collected, was just south of the point where air traffic controllers lost contact with the plane, which carried 239 people.
The two-kilometre long slick was the largest of several in the area. (AFP)
