GLOBAL MARKET - NEW YORK. Wall Street indexes ended lower, oil kept climbing and U.S. borrowing costs fell on Tuesday as U.S. President Donald Trump left the Group of Seven summit early and investors awaited a series of interest rate decisions by major central banks.

Trump returned to Washington a day before the summit ends as the Israel-Iran conflict intensified, saying U.S. patience was wearing thin but that he would not kill Iran's leader "for now."
