The US-Iran ceasefire is set to expire amid stalled negotiations, raising concerns about a potential escalation of conflict. The 60-day deadline for a peace deal has passed without an agreement, leaving both parties in a precarious situation. Brent oil prices surged to $91, reflecting tensions as Iran ruled out an extension of the interim deal and threatened further actions. Senior Iranian sources have insisted that discussions for a ceasefire extension are off the table, while US officials continue to seek a resolution. UN officials have urged both Washington and Tehran to resume talks to prevent a resurgence of hostilities, but analysts note that the chances of an agreement remain slim.
