A US Army attack helicopter crashed early Tuesday near the Strait of Hormuz, but President Donald Trump said the two crew members aboard were not injured in the incident near the strategic waterway that Iran has effectively closed during the war.What caused the crash of the Apache remained unclear in a West Asia still reeling after Iran and Israel exchanged fire the previous day in the biggest blow yet to the strained ceasefire in the Iran war. Iranian state television reported Tuesday that the Israeli attacks killed at least two members of the country’s air-defence units.
