A tenuous month-old ceasefire appears to be holding in the Iran war as diplomacy continues and Iran reviews the latest U.S. proposal. Bahrain hosts the U.S. Navy’s regional headquarters and says it arrested dozens of people it alleged were linked to Iran’s Revolutionary Guard. Washington on Saturday awaited an Iranian response to its latest proposal for a deal to end the war, reopen the Strait of Hormuz and roll back Tehran’s disputed nuclear program. Britain says it is deploying a warship to the Middle East to join a potential mission to protect commercial ships in the strait once hostilities end.
