Iran-aligned Iraqi armed group Kataib Hezbollah warned on Sunday it would resume attacks on U.S. troops in the region if the United States intervenes in the conflict between Israel and Iran.

"Hezbollah is committed to the ceasefire agreement, even though Israel has not respected this commitment over the past period," the spokesperson said. "It continues to kill, assassinate, and attack areas, including entering border villages and remaining at the five points."

Israel and Iran bombarded each other for a third day, with international concern growing that the conflict will spread across one of the world’s key oil-producing regions.
