US President Donald Trump has extended the Iran ceasefire until an Iranian proposal is submitted, reversing his previous hardline stance. The extension was requested by Pakistan, the host mediator, and Trump said he hoped to reach a "great deal" to end the war. Iran's response to the announcement was skeptical, with some officials calling it a "ploy to buy time" for a surprise strike. The ceasefire was set to expire today, and the situation remains uncertain, with oil prices climbing 3% on Tuesday due to concerns over the ongoing conflict.
