伊朗外交部：伊朗未攻擊地區內任何國家，軍事打擊僅針對美國據點，以迴應美國的攻擊。德黑蘭已多次敦促鄰國不要允許美國或以色列利用其領土對伊朗發動攻擊。

Switzerland and the United Kingdom agreed an updated free trade agreement, aiming to deepen economic ties between the two largest non‑EU West European economies. Negotiations, launched more than three years ago, were declared concluded and the accord was signed in Bern on Monday by UK Business and Trade Secretary Peter Kyle and Swiss Federal President and Minister of Economic Affairs Guy Parmelin. The pact builds on a 2023 financial services agreement and targets easier cross‑border operations for financial, technology, pharmaceutical and legal services through improved market access, reduced administrative barriers, strengthened data sharing and measures to facilitate labor mobility. The UK said bilateral trade exceeded £50bn last year (~$67bn), with roughly £30bn in goods. Officials estimate services trade could expand by about £5.2bn annually over the long term under the agreement.
