Iran says it won’t be participating in negotiations with the U.S. after it seized an Iranian cargo ship near the Strait of Hormuz. “While claiming diplomacy and readiness for negotiations, the U.S. is carrying out behaviours that do not in any way indicate seriousness in pursuing a diplomatic process,” said Esmaeil Baghaei, a spokesperson for the Iranian Foreign Ministry, on Monday, saying that the U.S. “violated the ceasefire from the beginning of its implementation.” President Trump bragged on Truth Social Sunday that the Navy destroyer USS Spruance intercepted the Iranian cargo ship Touska in the Gulf of Oman, claiming that the U.S. “stopped them right in their tracks by blowing a hole in the engine room.” The ship has been captured by the Marines, which Trump said is under Treasury sanctions for “illegal activity.” The two-week ceasefire between Iran and the U.S. is set to expire on Wednesday, and a senior Iranian source told Reuters that the U.S. blockade on Iranian ports was undermining the prospect of negotiations, and that Iran’s “defensive capabilities,” including missiles, were not open for discussion. Meanwhile, the U.S. is sending a delegation to Islamabad, Pakistan, including Vice President JD Vance, envoy Steve Witkoff, and Trump’s son-in-law Jared Kushner. Pakistan is deploying 20,000 police, paramilitary, and army personnel to secure the talks, but it could all be for nought if the ceasefire collapses and Iran refuses to take part in talks.
