Two rockets were fired on Monday at central Baghdad’s fortified Green Zone, which houses foreign embassies and government buildings, but there were no casualties or damage caused, security services said. There was no immediate claim of responsibility for the blasts. One rocket exploded inside the Green Zone and another landed in the Tigris river, a statement from Iraqi security services said. A rocket fired from eastern Baghdad landed in the area in May, close to the US embassy, and was also not claimed. Such incidents have been rare but sporadic in the Iraqi capital in recent years. Iraq, whose main allies are Washington and Tehran, fears it could be caught in the middle of any regional conflict between Iran and the United States. It hosts both US troops and paramilitary groups loyal to Tehran. The United States has blamed Iran for recent attacks including on oil installations in Saudi Arabia this month, which Iran denies. Both countries say they do not want war. There also has been a series of airstrikes on bases belonging to Iran-backed militias in Iraq that the militias have blamed on Israel and its US ally by extension. Israel, which frequently targets Iranian interests in neighboring Syria, has not confirmed its involvement in the airstrikes inside Iraq.
