Since the start of the war, Iran has blocked some oil tankers and attacked cargo vessels trying to pass through the strait, which has led to a huge spike in global oil prices.

Nearly a fifth of the world's oil supply typically passes through this vital oil export route.

bombed military targets on Iran's Khark Island Saturday.

might hit the island again, quote, just for fun, if Iran continues interfering with ships passing through the Strait of Hormuz.
