WASHINGTON (AP) — The United States attacked and seized an Iranian-flagged cargo ship it said had tried to evade a naval blockade near the Strait of Hormuz on Sunday, and Iran's joint military command vowed to respond, throwing a fragile ceasefire into question days before it expires.

It was the first interception since the U.S. began last week. Iran's joint military command called the armed boarding an act of piracy and a ceasefire violation, the state broadcaster said.
