Iran threatens new offensive while US rules out extending ceasefire deal

Stalled diplomacy over Iran’s nuclear programme and the future of the Strait of Hormuz raises the risk of renewed fighting and further disruption to global energy supplies.

Iran will shift to a “fully offensive” military posture because efforts to negotiate a permanent end to the war with the US have stalled, a senior Iranian official told Reuters on Monday, as Washington ruled out extending ‌a temporary ceasefire agreement.
