U.S. President Donald Trump said on Wednesday an interim agreement to end the war with Iran was ¡°over¡± after Tehran carried out new attacks on U.S. bases in the Gulf.

In a flare-up of hostilities that pushed oil prices up sharply, Iran said it had targeted U.S. military sites in Bahrain and Kuwait after U.S. forces struck Iranian targets in response to attacks on tankers in the Strait of Hormuz.

The attacks further ?undermined a shaky ceasefire agreement and dented hopes of turning the memorandum of understanding signed on June 17 into a permanent peace deal to end the war, which began with ?U.S.-Israeli airstrikes ?on Iran on Feb. 28.
