By Parisa Hafezi, Jana Choukeir and Ahmed Tolba DUBAI/CAIRO, July 29 (Reuters) - The United States and Saudi Arabia jointly struck Iran-backed groups in Iraq on Wednesday, and President Donald Trump vowed to "beat the fucking shit" out of Iran for firing on U.S. troops just days after he suspended airstrikes. Iran confirmed late Tuesday that it had fired on U.S. bases in Jordan and at ships in the Strait of Hormuz, and also spurned an Omani proposal to jointly manage the strait.
