Katyusha rocket fired into Baghdad Green Zone

A Katyusha rocket was fired Sunday into Baghdad's Green Zone housing government offices and embassies including the US mission, days after the United States evacuated staff from Iraq citing threats from Iran. Tensions between the US and Iran have been high since Washington withdrew last year from the 2015 nuclear deal between Tehran and major world powers, and they have soared in the past few weeks. Despite international scepticism, the US government has cited alleged threats from Iran, a long-time enemy of both Washington and its regional allies, including Israel and Saudi Arabia, but a powerbroker in Iraq.
