US Navy Seizes MV Touska; Iran Calls It "Piracy," Boycotts Islamabad Talks; Trump Declares Ceasefire Ends Wednesday

USS Spruance fires on and seizes Iranian container ship MV Touska in the Gulf of Oman after a six-hour standoff; Iran's foreign ministry labels it "piracy" and withdraws from the planned second-round Islamabad talks; Trump states the ceasefire expires Wednesday evening and a further extension is "highly unlikely."

April 20, 2026 became the most consequential day of the ceasefire period, with a single US naval operation simultaneously destroying the diplomatic track and pushing the countdown clock to near-zero. In the early hours of Monday (just after midnight Iran time), US Central Command announced that the guided-missile destroyer USS Spruance (DDG-111) had intercepted the Iranian-flagged container ship MV Touska in the Gulf of Oman, approximately 550 kilometres east of the Strait of Hormuz. The Touska — 294 metres long and owned by the Islamic Republic of Shipping Lines (IRISL), a company sanctioned by the US, EU, and UK — had departed Chinese ports (Shanghai and Macau) before transiting Port Klang, Malaysia, and was bound for Bandar Abbas. Analysts at Kpler noted that Gaolan Port in Zhuhai, one of the ship's loading points, is associated with sodium perchlorate exports — a precursor for solid rocket fuel. CENTCOM stated that Spruance issued repeated warnings over a six-hour period and, after ordering the crew to evacuate the engine room, fired its 5-inch (127mm) MK 45 gun at the vessel's engine room, disabling its propulsion. US Marines from the 31st Marine Expeditionary Unit then fast-roped onto the deck via MH-60S Seahawk helicopters launched from the amphibious assault ship USS Tripoli (LHA 7). CENTCOM released grainy video footage of the boarding. Since the blockade began on April 13, the US had directed 25 commercial vessels to turn around; the Touska was the first to be forcibly seized. The Iranian response was immediate and categorical. Foreign Ministry spokesman Esmaeil Baghaei appeared at a Monday morning press conference and called the seizure "an act of piracy in international waters" that violated both the ceasefire agreement and international law. He stated that Iran had "no plans for the next round of negotiations," adding: "We don't believe in deadlines or ultimatums to secure Iran's national interests. We don't trust Washington." The Iranian military's top joint command warned that "the armed forces of the Islamic Republic of Iran will soon respond and retaliate against this armed piracy by the US military," citing crew safety as the only current limiting factor. President Masoud Pezeshkian, speaking on state television, said Iranians "do not submit to force" and accused the US of seeking "Iran's surrender." In Washington, Trump made no apology for the seizure. Speaking to Bloomberg, he confirmed the ceasefire expires "Wednesday evening Washington time" and said a further extension was "highly unlikely" without a deal. Trump stated: "I'm not going to be rushed into making a bad deal. We've got all the time in the world." He announced that Vice President JD Vance, special envoy Steve Witkoff, and Jared Kushner were still expected to travel to Islamabad on Tuesday for a second round of talks — a trip now rendered uncertain by Iran's withdrawal from the process. The White House described the situation as "fluid." Press secretary Karoline Leavitt said conversations were still "productive and ongoing," a description that sat awkwardly against Baghaei's explicit rejection of further talks. China's foreign ministry spokesman Guo Jiakun voiced Beijing's concern, calling the Hormuz situation "sensitive and complicated" and urging parties "to abide by the ceasefire agreement in a responsible manner" and avoid further escalation. The China angle was sharpened by the Touska's cargo origin: the ship had loaded in Chinese ports, and Trump's statement that troops were "seeing what's on board" implied the contents could complicate Beijing-Washington relations further. Oil markets reacted sharply. Prices surged as the Strait of Hormuz entered its third consecutive day with virtually no commercial traffic. Trump contradicted his own Energy Secretary Chris Wright, who had projected gasoline prices might not fall below $3 per gallon until 2027, by insisting prices would fall "as soon as this ends." In Lebanon, a second round of direct Israel-Lebanon peace talks was scheduled for Thursday in Washington, with delegations led by ambassadors. Lebanese President Joseph Aoun insisted these negotiations must remain "separate from any other negotiations," saying Lebanon faces "two options: either the continuation of the war or negotiation to put an end to this war."
