TOKYO (AP) — Global shares sank on Monday after Wall Street ended last week with its worst day since October, while oil prices jumped more than $4 as fighting flared between Israel and Iran.

South Korea’s Kospi led the global retreat, plunging 8.3% on heavy selling of technology shares and extending losses that on Friday gave the S&P 500 its biggest single day drop in months.

The U.S. war with Iran has essentially blocked crude oil shipments from moving through the Strait of Hormuz.
