US-Iran Ceasefire Expires with No Deal; Trump Threatens to Bomb Iranian Power Plants and Bridges

The fragile two-week US-Iran ceasefire — in place since April 7 — expired on April 21 with no deal reached. A second round of talks in Islamabad ended after approximately 21 hours with US negotiators departing without agreement: Iran refused to send delegates to the formal negotiations, citing the US naval blockade as a ceasefire violation and insisting negotiations could not occur 'under the shadow of threats.' Trump said it was 'highly unlikely' he would extend the ceasefire without a deal, and threatened to 'knock out every single Power Plant, and every single Bridge, in Iran' if hostilities resumed, adding that US forces were 'raring to go.' VP JD Vance, Steve Witkoff, and Jared Kushner had traveled to Islamabad but Iranian officials were largely absent from the formal table. Iran's Foreign Ministry insisted no active negotiations were taking place. The core sticking points remained: the US demanded a 20-year suspension of all Iranian uranium enrichment; Iran demanded an end to the naval blockade and war reparations before any talks. WTI crude rose toward $93–95/barrel as markets priced in rising risk of renewed strikes; the S&P 500 moved into the red, shedding early gains as the ceasefire deadline passed without resolution.
