Authorities have confirmed that the oil slick found about 100 nautical miles off the coast of Kelantan is not from the missing MH370 aircraft.

The Malaysian Maritime Enforcement Agency (MMEA) said samples taken from the scene confirmed that the oil slick came from a ship.

MMEA Eastern Region chief First Admiral Datuk Nasir Adam told reporters at a press conference that the samples are not from the Malaysian Airlines (MAS) aircraft which went missing since Saturday.

“The result of the analysis is negative,” he said at the MMEA headquarters in Pasir Puteh, Kelantan.

Samples of the oil slick were sent to the Chemistry Department in Petaling Jaya as there were no such facilities in Kelantan and Terengganu.

MH370 went missing after it lost all communications with air traffic control about an hour after taking off at 12.41am from Kuala Lumpur. It was supposed to arrive at 6.30am.

The plane, carrying 239 passengers and crew, is yet to be located.

Authorities have not ruled out the possibility of a terrorist attack and are investigating at least two individuals who have boarded MH370 with stolen passports.

Malaysian authorities are said that they are working closely with international intelligence officers, including those from US and China.
