The U.S. air strikes in Iraq will only have "minimal impact" on ISIS, the Islamic militants that overrun most of the area. President Barack Obama has authorised "limited strikes" against the militants who are in immediate areas targeted by the U.S. military.

According to Army Lt. Gen. William Mayville, he expects ISIS to move elsewhere. He said he doesn't want to suggest that U.S. forces have effectively contained the threat posed by the Islamic militants who were beheading and burying children and women alive.

Despite the continuous airstrikes for four days, U.S. lawmakers fear an impending attack by ISIS on American soil. U.S. Senator Lindsay Graham said that unless a more decisive action is taken against Islamic militants, the threat will always be there.

Reports said ISIS has killed at least 500 Yazidis, a religious minority group in Iraq for refusing to convert to Islam. Lawmakers said the "bloodthirsty Islamic fanatics" in the Middle East are considered U.S. threats.

After Pres. Obama ordered airstrikes on August 9 to save Yazidis from genocide, lawmakers had accused the president of "not doing enough" against the Islamic militants. Rep. Pete King slammed Mr Obama for getting involved in Iraq and called it a "shameful" act of the president. He said ISIS was "more powerful than Al Qaeda" with the 9/11 tragedy. The congressman said ISIS has more money, weapons and fighters than Al Qaeda. He feared ISIS is capable of launching a U.S. attack.

ISIS has been called many names, among them "the face of evil", in response to its shocking actions of beheading children and mounting their heads on sticks in Iraq's Mosul Park. The Iraqi government has acquired images showing clear evidence that ISIS has executed at least 500 Yazidis after taking over Sinjar.

Yaizidis are among Iraq's religious minority groups and of Kurdish descent. Their religious beliefs are taken from Christianity, Judaism and Zoroastrianism. They are one of the world's oldest religious communities and have long suffered persecution for their beliefs. Reports said many Muslims describe Yazidis as "devil worshippers." The Yazidis fled their homes and sought refuge in the mountains when ISIS forces seized Sinjar.
