伊拉克部队和民兵武装星期二继续对提克里特附近的伊斯兰国组织发动攻势，努力收复这个去年6月被激进分子占领的城市。
地面部队分多路进攻，但军事指挥官说，路边炸弹延缓了进攻速度。
参加这次行动的有大约3万名伊拉克安全部队、什叶派民兵和库尔德武装。伊拉克空军也对目标展开了空袭行动。
特克里特的胜利将为伊拉克部队挺进摩苏尔提供一个前沿阵地。摩苏尔是伊拉克第二大城市，也是伊斯兰国激进组织的大本营和指挥中心。
提克里特是2003年被废黜并处死的伊拉克前独裁者萨达姆·侯赛因的家乡。
Iraqi troops and militia fighters continued their offensive against the Islamic State group near Tikrit on Tuesday, as they try to recapture the city that fell to the militants last June.
Ground troops have been advancing on multiple fronts, but military commanders said their progress is being slowed by roadside bombs.
An estimated 30,000 members of Iraq's security forces, Shi'ite militias and Kurdish peshmerga fighters are taking part in the operation that also includes airstrikes from Iraq's air force.
A victory in Tikrit would be a geographic stepping stone for Iraqi forces to approach Mosul, Iraq's second-largest city that serves as a stronghold and nerve-center for the Islamic State group.
Tikrit is also the hometown of former Iraqi dictator Saddam Hussein, who was executed after his ouster in 2003.
