iranian soldiers are reported to be helping iraqi kurdish fighters try to retake the northern town of jal outlina from the islamic state group. iran denies that it has troops in iraq. we have more from kirkuk. >> well, kirkuk is a very volatile province, a province disputed by many side - the central government and the kurds. there were three explosions on saturday. one of them in a civilian neighbourhood. the other two targetting a convoy of peshmerga fighters. we have to remember the peshmerga are at war with the islamic state group. they share a border, and there are many front lines. they are not in the north. further south the iraqi army is engaged in a war with sunni armed groups much this is happening as politicians in baghdad are trying to get the political process on track, trying to farm an inclusive government. one that all of iraq's communities accept, because unless all these communities unite, then the security situation will deteriorate further. >> this family has been living in this room for almost three months now, moving to kirkuk when their home town turned into a battle ground
