U.S. equities fell Thursday as markets turned cautious after explosions in Afghanistan and ahead of a Federal Reserve gathering that may provide more clues about its approach to paring stimulus.
The S&P 500 and Nasdaq 100 slid as U.S. and civilian casualties were reported from blasts outside the Kabul airport, escalating tensions as the U.S. evacuates the area. The decline came after non-voting members of the Federal Open Market Committee also made hawkish monetary comments, urging the Fed to start tapering its asset purchase program. Energy shares led the decline as crude oil fell. Treasuries were little changed and the dollar rose.
