Negotiations between the United States and Iran appeared uncertain on Tuesday as both sides sent mixed signals and leaders exchanged threats, while the wider regional repercussions continued to strain energy markets and diplomatic ties.
Diplomatic scene and talks
US President Donald Trump said talks with Iran would resume in Pakistan and that he felt no pressure to force a deal as a 14-day ceasefire neared expiration on Wednesday. Media reports said Vice President J.D. Vance was expected to travel to Islamabad to meet Iranian officials.
Iran’s parliament speaker and chief negotiator Mohammad Bagher Qalibaf rejected what he described as US attempts to force a capitulation, saying Tehran had prepared ‘new cards on the battlefield.’ State television denied any Iranian delegation had yet departed for Islamabad, and hardliners reacted angrily after the US Navy seized an Iranian container ship over the weekend.
Germany urged Iran to accept the US invitation to hold constructive talks in Islamabad. German Foreign Minister Johann Wadephul said reopening the Strait of Hormuz was in Iran’s interest and criticized Tehran’s near-blockade of the waterway, adding that Europe stood ready to help secure it once hostilities end.
Regional diplomacy and ceasefires
Washington is reported to be hosting further negotiations between Israel and Lebanon to try to cement a fragile, US-mediated ceasefire; direct talks between the two countries were held earlier in April for the first time in decades. Meanwhile, EU foreign ministers met to discuss overlapping Middle East conflicts, including the campaign against Iran, the standoff in the Strait of Hormuz, and fighting between Hezbollah and Israel in Lebanon. Lebanese Prime Minister Nawaf Salam joined the session to brief ministers on conditions in his country.
EU energy and economic fallout
European officials said they are preparing contingency plans for looming fuel shortages. The European Commission is considering authorizing imports of US jet-fuel grade Jet A, not currently approved in the bloc, to reduce reliance on Middle Eastern supplies. The move follows warnings from the International Energy Agency and airlines that aviation fuel shortages could hit Europe within weeks if the Strait of Hormuz remains effectively blocked.
IEA chief Fatih Birol described the situation as one of the largest energy crises in history, saying disruptions tied to the Iran war compounded earlier shocks such as the Russia–Ukraine conflict and had produced major shortages in oil, gas and key commodities like fertilizer. He warned of higher inflation and slower growth, with developing countries especially vulnerable.
The European Commission is expected to table measures covering airport slot rules, anti-tankering practices, passenger rights and public service obligations to guide responses if jet fuel supplies tighten.
EU-Israel relations
Spain and Ireland have proposed suspending parts of the EU’s cooperation agreement with Israel in reaction to Israeli operations in Lebanon and the occupied Palestinian territories. Wadephul called a full suspension ‘inappropriate’ and argued for a calibrated mix of constructive engagement and criticism. A complete suspension would require unanimity among EU member states, while narrower elements of the deal could be altered by a qualified majority.
Human rights and security developments
Iran executed a man identified by the judiciary as Amir Ali Mirjafari, accused of leading a network linked to Israeli intelligence and of an arson attack on Tehran’s Gholhak Grand Mosque during January protests. The execution was among several carried out after the unrest that Tehran has blamed on foreign interference.
Outlook
With the ceasefire deadline looming, the prospect of renewed diplomacy remains unclear. Washington and Tehran have both signaled openness to further talks but also a willingness to continue military measures, complicating mediation efforts. At the same time, the conflict’s spillover effects — from potential aviation fuel shortages and broader energy shocks to shifts in EU-Israel relations and renewed regional mediation efforts — are forcing governments and agencies to prepare contingency plans as the situation remains highly unstable.
