Iran live updates: CENTCOM denies IRGC claim of strikes on US destroyers

The price of global oil hit $100 a barrel on Wednesday morning, the first time the price reached that threshold since July 24.

Brent crude oil prices, a benchmark for global trading, climbed by about 2.7%, trading at about $100.57 a barrel for contracts with November dates.

U.S. oil traded at about $95 a barrel, up by about 2%.

The price of global oil has been rising throughout the week amid intensified exchanges between the U.S. and Iran centered on the Strait of Hormuz, plus an escalation of fighting between Iran-backed Houthi rebels and Saudi-backed government forces in Yemen.

A U.S. official said a missile attack carried out by Iran toward Jordan was "ineffective."

“Iran’s response was ineffective in face of integrated air and missile defenses," the official said. "Iran fired missiles toward Jordan. American forces have 100% accountability at all locations in Jordan."

The Iranian missile barrage came after the U.S. said it destroyed five Islamic Revolutionary Guard Corps oil tankers on Tuesday in response to the targeting of a U.S. Navy warship.

In an earlier statement, the Jordanian Armed Forces said Jordanian air defense systems intercepted 20 ballistic missiles launched toward Jordanian territory, successfully intercepting and destroying 18 of them, while two missiles fell in remote areas.

No loss of life was recorded, according to the Jordanian army statement.

In response to U.S. strikes on Iranian oil tankers, the Islamic Revolutionary Guard Corps claimed to have fired at U.S.-related targets in Jordan.

The targets included a hangar for fighter jets at the Al-Azraq base, it said.

U.S. Central Command said its forces destroyed five Islamic Revolutionary Guard Corps oil tankers on Tuesday in response to the targeting of a U.S. Navy warship.

Four of the tankers were in the Gulf of Oman, while one was near Kharg Island, CENTCOM said.

"American forces directed the crews to abandon ship before the vessels were struck and rendered inoperable," CENTCOM said.

The targeted U.S. Navy warship evaded Iranian missile attacks and no American forces were harmed, according to CENTCOM.
