Washington: The United States intends to launch further strikes at Iran-backed groups in the Middle East, the White House national security adviser said on Sunday, after hitting Tehran-aligned factions in Iraq, Syria and Yemen over the last two days. The United States and Britain unleashed attacks against 36 Houthi targets in Yemen, a day after the US military hit Tehran-backed groups in Iraq and Syria in retaliation for a deadly attack on US troops in Jordan. “We intend to take additional strikes, and additional action, to continue to send a clear message that the United States will respond when our forces are attacked, when our people are killed,” White House National Security Adviser Jake Sullivan told NBC’s “Meet the Press” program on Sunday.Washington: The United States intends to launch further strikes at Iran-backed groups in the Middle East, the White House national security adviser said on Sunday, after hitting Tehran-aligned factions in Iraq, Syria and Yemen over the last two days.
