Three rockets on Wednesday targeted rebel Iranian Kurdish forces not far from Arbil airport, the capital of Iraqi Kurdistan and a location where US soldiers are based, two sources said. "Tonight three rocket attacks on nearby locations of #Iranian opposition" close to Arbil airport "is yet another escalation to disrupt security in #Iraq and #IraqiKurdistan," Hoshyar Zebari, a former Iraqi foreign minister and a politician in northern Iraq's autonomous Kurdish region, said on Twitter. There was no immediate indication of the origin of the rocket fire, but Souran Ali, a commander of the Iranian Kurdish opposition group targeted by the rockets, also said three rockets had been fired, without causing casualties. str-sbh/dwo/pjm
