Tehran vowa to respond after USS Spruance fires on Iranian-flagged cargo ship allegedly running strait of Hormuz blockade. Key US politics stories from Sunday 19 April

America’s benchmark oil contract West Texas Intermediate (WTI) surged late on Sunday after Iran accused the US of having broken a ceasefire in place since early April.

WTI crude was trading up 7.5% at $90.17 per barrel by 8pm ET, while international oil benchmark Brent North Sea crude gained 6.%5 to $96.27 per barrel.

Iran’s military vowed to respond after the destroyer USS Spruance on Sunday fired on an Iranian-flagged cargo ship in the Gulf of Oman that tried to evade the US naval blockade. The strait of Hormuz, a vital conduit for the world’s oil and liquefied natural gas, has been virtually closed since the start of the US-Israeli war with Iran.

The US military took custody of an Iranian-flagged container ship that attempted to get past an American blockade near the strait of Hormuz, Donald Trump announced on Sunday.
