Malaysia (WSYR-TV/CNN) - Search teams resumed their search at first light on Sunday for missing Malaysia Airlines Flight 370.
The plane lost contact while flying from Kuala Lumpur to Beijing.
The plane was carrying 227 passengers, including 3 Americans, and 12 crew members.
On Sunday, aircrafts searched an area of the South China Sea for any sign of where the flight may have gone down, Azharuddin Abdul Rahman, the director general of civil aviation in Malaysia, told reporters
The closest things to clues in the search for the missing jetliner are oil slicks in the Gulf of Thailand, about 90 miles south of Vietnam's Tho Chu Island -- the same area where the flight disappeared from radar early Saturday morning.
Malaysian authorities have not yet confirmed the Vietnamese report, Rahman said.
20 of the passengers aboard the flight work with Freescale Semiconductor, a company based in Austin, Texas. The company said that 12 of the employees are from Malaysia and eight are from China.
Because of the Americans aboard the flight, the FBI has offered to send a team of agents to Malaysia to support the investigation into the disappearance if asked, a U.S. official familiar with the issue told CNN on condition of anonymity. Earlier, an official had said FBI agents were heading to the area.
The FBI is not ruling out terrorism or any other issue as a possible cause in the jetliner's disappearance, the official said.
