SINGAPORE (Reuters) - Singapore and Australia suspended operations of all Boeing 737 MAX aircraft in and out of their airports on Tuesday, and Indonesia and China grounded their fleets of the U.S. planemaker' s latest model after it suffered a second fatal crash in less than five months.

The scare has wiped billions of dollars off the market value of the world's biggest planemaker, as the Boeing Co share closed 5 percent down on Monday having fallen by as much as 13.5 percent at one point.
