Baghdad , Iraq ( CNN ) -- A Sunni town north of Baghdad that has been surrounded by ISIS for more than two months came under heavy attack on Monday , local police and residents said . At about 9 a.m. , a suicide bomber in a seized military Humvee struck a dirt berm that was built as part of the defenses around the southern part of Dhuluiya . The bombing cleared the way for a second suicide bomber in another Humvee to drive into the center of the town and strike the market area . At least nine people were killed and more than 70 others were wounded in the two bombings . . Shaalan al-Jibouri , a resident of Dhuluiya and a local journalist , explained the situation to CNN from inside the town . He said ISIS seized the town in June , but on June 18 , the al-Jibour tribe , along with the local police , pushed ISIS out of the southern part of the town and took control of the area , while ISIS remained in control of the northern part . Since June , al-Jibouri said , the southern part of Dhuluiya has been besieged and under constant attack by ISIS . Local officials have counted 72 attacks , including hundreds of mortar and artillery shell strikes . The attack on Monday , he said , was the worst since the ISIS offensive began . On July 16 , he said , ISIS blew up a vital bridge connecting Dhuluiya to the predominantly Shiite town of Balad about 10 kilometers ( 6 miles ) to the west . Al-Jibouri said the bridge was a lifeline for the town and even though Balad is a Shiite town , its local officials and residents have supported and assisted residents of Dhuluiya throughout the siege . He described a dire humanitarian situation in the part of Dhuluiya that has no medical care and having to move people to Balad for treatment there . The destruction of the bridge has forced them to use small boats to move the injured and get supplies , which has been very difficult , he said . Al-Jibouri said the people of his town and its police force are determined to continue the fight , with women and young boys taking up arms to defend their home . `` We lived through a bitter experience in 2006 under these people . They did not distinguish between security forces and civilians . They massacred people then and they will do it again . ... We will not allow them to enter the town . Dhuluiya will continue its resistance until the last breath , over our dead bodies will they enter this town . '' Al-Jibouri 's wife and 16-year-old daughter were wounded when an artillery shell hit close to their home last week . He said local officials have repeatedly asked for government support but have received only `` empty promises . '' `` In the name of humanity we call on President Obama , who says they are the protectors of humanity -- where are your planes , your missiles ? '' `` Why this terrorism , why are our children being killed , our homes destroyed ? We call on the American people to pressure their government to help us . '' A number of people in the room with him also said they want the United States to help them , saying even if it 's American troops , `` we welcome them . '' They accused the Iraqi government of a double standard , apparently a reference to the fact that about a week ago , Iraqi troops broke the ISIS siege in the town of Amerli , which is predominantly Shiite .
Town was taken over by ISIS in June , but police and local tribe regained control of part of it . Residents of Dhuluiya say since then , ISIS has attacked relentlessly . Monday , suicide bombers hit the downtown market area , killing at least 9 . The Associated Press contributed to this report.
