U.S. President Donald Trump has accused Israel of attacking Iran's South Pars gas field without US and Qatari involvement. He also warned against further attacks on Iran's facilities unless Iran attacks Qatar. The Israeli government has not yet claimed responsibility for the attack. Iran shares the South Pars field with Qatar, which has rebuked Israel for its "dangerous and irresponsible" attack. The war against Iran has caused significant disruption to oil supplies and resulted in a surge in prices.
