US Defense Secretary Pete Hegseth said Thursday there is no "time frame" for ending the US-Israeli war against Iran, which was launched three weeks ago.

The Pentagon is seeking $200 billion in additional funds for the Iran war, a senior administration official says.

The department sent the request to the White House, according to the official, who spoke on condition of anonymity to discuss the private information.

Iran intensified its attacks on oil and gas facilities around the Gulf on Thursday, dramatically raising the stakes in a war that is sending shock waves through the global economy.

The strikes, in retaliation for an Israeli attack on a key Iranian gas field, sent fuel prices soaring and risked drawing Iran's Arab neighbors directly into the conflict. Tehran's targeting of energy production further stressed global supply already under pressure because of Iran's stranglehold on the Strait of Hormuz, a strategic waterway through which a fifth of the world's oil is transported.

European leaders doubled down Thursday on refusing to join the United States and Israel military campaigns in the Middle East as they met in Brussels to grapple with rising oil and gas prices caused by the war.

European leaders have deflected entreaties from U.S. President Donald Trump to send military assets to secure the Strait of Hormuz, a key waterway for the global flow of oil, gas and fertilizer. However, rising energy prices because of the war and fears in Europe of a new refugee crisis have pushed leaders to make the Middle East a priority at the summit.

Saudi Arabia has not ruled out military action in response to repeated missile and drone attacks from Iran, Foreign Minister Prince Faisal bin Farhan said on Thursday.

Speaking to reporters following a meeting in Riyadh of foreign ministers from the region, Prince Faisal said that Iran "tries to pressure its neighbors" with attacks.

U.S. President Donald Trump pledged the U.S. would "massively blow up the entirety" of the world's largest gas field if Iran attacks Qatar again.

Trump made his threat on social media Wednesday night against Iran's South Pars natural gas field after Iranian missiles hit Qatar. The Iranian attack was in retaliation for an Israeli attack on the South Pars field earlier Wednesday.

Iran's military said it would target energy infrastructure across the Gulf following a U.S.-Israeli attack on its facilities at a major gas field, state television reported on Wednesday.

U.S. President Donald Trump angrily suggested Wednesday that he could leave U.S. allies to secure the Hormuz strait on their own since they have refused to fight alongside U.S. forces against Iran in the crucial shipping lane.

Saying the United States doesn't need the strait -- a major global oil shipping pathway -- Trump wrote on his Truth Social site that he could "let the Countries that use it" find a solution.

Germany and France on Wednesday called for de-escalation of the Middle East war with Germany's top diplomat warning of a "crisis of the gravest order" if global supply chains continue to be disrupted.

Doha on Wednesday condemned attacks on an Iranian facility on the Gulf coast serving a massive gas field it shares with Qatar.
