Asian markets tumble as bank worries spread from Wall Street

Asian markets sank again Friday following a rout on Wall Street as signs of trouble at a regional US lender sparked concerns about the wider sector as the Federal Reserve ramps up interest rates.

The sell-off comes as traders nervously await the release of US jobs data later in the day, with many fearing a forecast-beating figure could press the central bank to ramp up borrowing costs more than previously thought.
