Iran launched fresh attacks across the Middle East on Monday and threatened "devastating" retaliation, after U.S. President Donald Trump's expletive-laced warning that Tehran must reopen the Strait of Hormuz.

U.S. President Donald Trump on Sunday appeared to extend by 24 hours his deadline for Iran to make a deal to reopen the Strait of Hormuz or face devastating infrastructure attacks.

U.S. President Donald Trump said Sunday he believes there is a "good chance" of making a deal with Iran on Monday, ahead of his deadline for Tehran to reopen the Strait of Hormuz or face heavy bombing.

U.S. President Donald Trump said Sunday that U.S. forces had safely recovered a second airman downed in Iran, calling it "one of the most daring Search and Rescue Operations in U.S. History".

U.S. President Donald Trump said that "many" of Iran's military leaders were killed in a huge strike on the Islamic republic's capital.

Critical infrastructure across the Gulf came under attack from Iran on Sunday with damage reported at civilian facilities in the United Arab Emirates, Bahrain and Kuwait.

In the usually lively alleyways of Jerusalem's Old City, silence reigned on Easter Sunday, with the holiday overshadowed by war and restrictions on access to the Holy Sepulcher, where the faithful commemorate Christ's crucifixion and resurrection.

Over the last ten days the U.S. and Iran have held indirect negotiations through Pakistan, Egypt and Turkey to try and reach a deal of a ceasefire in return for opening the strait of Hormuz. No significant progress has been achieved so far, U.S. news portal Axios reported on Saturday.

U.S. President Donald Trump on Saturday reminded Iran of the 10-day ultimatum he had issued for it to accept a deal that would stop the war.

"Remember when I gave Iran ten days to MAKE A DEAL or OPEN UP THE HORMUZ STRAIT. Time is running out - 48 hours before all Hell will reign down on them," Trump said in a post on the Truth Social platform.

Mediators from Pakistan, Turkey and Egypt are still working on a ceasefire plan between the U.S. and Iran, the Israeli Public Broadcasting Corporation reported on Saturday.
