Uncertainty over whether the United States and Iran will resume negotiations in Pakistan persisted on Tuesday as both sides issued mixed signals and leaders traded threats, while the wider regional fallout continued to strain energy supplies and diplomatic ties.
Diplomatic scene and talks
– US President Donald Trump said talks with Iran would resume in Pakistan and insisted he was under no pressure to clinch a deal as a 14-day ceasefire approached its expiry on Wednesday. Axios reported US 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 surrender, saying Tehran had prepared “new cards on the battlefield.” Iranian state television also ran an alert denying that 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 take up the US offer to hold constructive talks in Islamabad. German Foreign Minister Johann Wadephul said it would be in Iran’s interest to negotiate and criticized Tehran’s virtual blockade of the Strait of Hormuz, urging its reopening and saying Europe stood ready to help secure the waterway after the conflict ends.
Regional diplomacy and ceasefires
– The US is reported to be hosting fresh negotiations between Israel and Lebanon aimed at cementing a fragile US-mediated ceasefire. Direct talks between the two countries were held earlier in April for the first time in decades.
– EU foreign ministers convened to discuss the multiple Middle East conflicts, including the US-Israel campaign against Iran, the standoff over the Strait of Hormuz, and hostilities involving Hezbollah and Israel in Lebanon. Lebanese Prime Minister Nawaf Salam joined the meeting to brief ministers on the situation in his country.
EU, energy and economic fallout
– European Commissioner for Sustainable Transport and Tourism Apostolos Tzitzikostas said the EU was considering authorizing imports of US jet fuel grade Jet A, currently not approved by the bloc, to reduce dependence on Middle Eastern supplies. The move follows warnings from the International Energy Agency (IEA) and airlines that aviation fuel shortages could hit Europe within weeks if the Strait of Hormuz remains effectively blocked.
– Fatih Birol, head of the IEA, described the situation as the biggest energy crisis in history, saying the combined effects of disruptions linked to the Iran war and earlier shocks such as the Russia–Ukraine conflict had created major shortages in oil, gas and commodities like fertilizer. He warned of higher inflation and slower growth, particularly in developing countries.
– The European Commission was set to present a package of energy and transport measures to guide responses on airport slots, anti-tankering, passenger rights and public service obligations in the event of jet fuel shortages.
EU-Israel relations
– Spain and Ireland proposed suspending the EU’s cooperation deal with Israel in response to Israeli actions in Lebanon and the occupied Palestinian territories. German Foreign Minister Wadephul called a full suspension “inappropriate,” arguing for constructive, critical dialogue instead. A complete suspension would require unanimity among EU member states; parts of the deal related to closer trade ties might be easier to suspend by weighted 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 by Iranian authorities following the anti-government unrest that Tehran has blamed on foreign interference.
Outlook
With the ceasefire deadline looming, talks remain in doubt. Washington and Tehran have signaled both openness to further negotiations and willingness to continue military measures, complicating diplomatic efforts. Meanwhile, the conflict’s wider consequences — from potential aviation fuel shortages and global energy shocks to shifting EU-Israel ties and renewed regional mediation efforts — are shaping an unstable international response as ministers and agencies seek contingency plans.
