BEHIND THE LINES: But who exactly carried out this attack? Who is targeting US forces in Iraq, Syria, and Jordan?
Kanaani said the US attacks were designed "to overshadow the Zionist regime's crimes in Gaza." He did not indicate if Iran would take any action in response.
The strikes hit targets including command and control centers, rockets, missiles, and drone storage facilities, as well as logistics and munition supply chain facilities, the US military said.
US forces were waiting for the right weather conditions to conduct the strikes, Lt.-Gen. Douglas A Sims said.
While the US strikes did not target any locations inside Iran, they are likely to increase concern about tensions in the Middle East.
The US has reportedly approved plans for multi-day strikes in Iraq and Syria against multiple targets, including Iranian personnel and facilities in those countries.
US officials have weighed how to punish Iran-backed militias without triggering a wider war.
