The United States launched airstrikes against Iran, and Tehran fired back at countries in the region. The escalating attacks threatened to derail efforts to end the war, as US President Donald Trump warned that Tehran would "pay the price" for stalled peace negotiations. Trump's warning came hours after Bahrain, Kuwait and Jordan - all of which host US troops - came under Iranian fire. It was the second time this week that back-and-forth strikes have tested a two-month ceasefire. On Monday, Iran and Israel targeted each other.
It was not clear what Trump's post on Truth Social would mean for Tehran, and the comments underlined the American leader's whipsaw approach to the war. He suggested that a deal to end the conflict could be reached in a matter of days.
Iran, meanwhile, has proved resilient despite having faced weeks of heavy bombing. It is betting that its ability to effectively close the Strait of Hormuz - a crucial passageway for the world's oil and natural gas - gives it a strong bargaining chip. Still, both countries seem to be looking for a way to end the conflict - if they can manage to sell it as a win at home. But Israeli Prime Minister Benjamin Netanyahu appears intent on pursuing much more difficult goals: the collapse of Iran's theocratic government, the elimination of its nuclear programme, and the destruction of the Iranian-allied Hezbollah militant group in Lebanon.
