GLOBAL MARKETS-Global Shares Slide, Yields Climb as Gulf War Intensifies

GLOBAL MARKET - LONDON. Global shares slid on Monday while U.S. bond yields hit eight-month peaks as the U.S. and Iran traded escalating threats and Israel planned for "weeks" more fighting, sending oil prices on another roller-coaster ride.

Iran on Sunday said it would strike the energy and water systems of its Gulf neighbours if U.S. President Donald Trump followed through with a threat to hit Iran's electricity grid within 48 hours, extinguishing any hope of an early end to the war, now in its fourth week.
