WASHINGTON, July 26 (Xinhua) -- Four U.S. service members have been killed and 207 others have been wounded since the U.S. military resumed hostilities against Iran in July, according to military casualty statistics updated by the Department of Defense on Sunday.

According to the Pentagon's Defense Casualty Analysis System, as of July 25, the U.S. military operation "Epic Fury" against Iran had resulted in 14 U.S. military personnel killed and 417 wounded.

The database recently added a new "Overseas Operations" tracking category, which separately compiles U.S. military casualties since July 7, listing four deaths and 207 wounded. However, this new category only lists the names of the deceased and does not provide specific details such as the time, location, or cause of the casualties.

Although all four deceased have been confirmed to have died in the new round of U.S.-Iran conflict, the U.S. Department of Defense has not yet confirmed whether all the wounded personnel are related to the U.S.-Iran conflict.

Under U.S. law, the president generally may not engage U.S. forces in hostilities for more than 60 days without congressional authorization. According to media reports, the Trump administration sent a letter to Congress on July 10 stating that Iran's attack on three merchant vessels transiting the Strait of Hormuz on July 7 violated a previous ceasefire arrangement. Based on this, the White House defined July 7 as the start date of a new round of hostilities with Iran.
