In defiance of ongoing attacks across the country, the U.S. officials iterated that Iraqi army is able to deal with security issues on their own. But local analysts worried that insurgents will further exploit the dragged-on political vacuum and stage more devastating attacks.

Qaida goes more rampant

The insurgents, who have been lying low months ago, are changing into a rampant and high profile style in recent crimes.

The so-called Islamic State of Iraq, a al-Qaida local branch, has claimed more than five major attacks launched on banks and security forces, while more provocatively, criminals took credit by rising their black flag in central Baghdad before fleeing the scene, in day time.

The new spate of bombings and attacks by al-Qaida groups coincided with the drawdown of U.S. troops, as the same goal remains: to undermine people's confidence in the serving government led by Nuri al-Maliki.

"The recent increase of violence showed that Maliki has failed to decrease the violence, which entails him to let others to form the new government to take the responsibility providing security and stability for Iraqis," Dr. Hani Ashur, a political advisor of the Iraqia List bloc headed by Ayad Allawi, told Xinhua in an interview.

But different from the past few months, insurgents have showed some new characters in their act of crimes.

The recent attacks are more organized and coordinated. Besides, a series of robbery of bank, gold stores and blood station, indicating that al-Qaida is launching crimes with more practical goals, not just to reignite sectarian violence, but also to reorganize and reoccupy their territory in Iraq after Americans left. They are using money, fear, instability and everything they can get to lure and force people back.
