ANNOUNCER: From ABC News, This Week with George Stephanopoulos begins now.
MARTHA RADDATZ: Good morning. I'm Martha Raddatz in Baghdad where the battle for control of Iraq has taken a dire turn. The jihadist group ISIS gaining new ground in the last 48 hours, capturing four key town near the Syrian border, and now threatening not only this country, but the entire region and the U.S. homeland with its growing strength.
We have team coverage of the latest developments, including breaking details on those U.S. special forces preparing to advise the Iraqi army.
But we begin here in Baghdad where Shiite militias took to the streets this weekend in a show of force.
RADDATZ: Members of the Mehdi Army, who once led the fight against Americans in Baghdad's Sadr City now vowing to stand up against ISIS, the jihadist fighters threatening Baghdad's borders.
But ISIS gained critical new ground this weekend. After wiping out an entire Iraqi brigade, ISIS now controls al Qa'im on the Syrian border, giving the terror group the ability to move weapons into Iraq from Syria.
And in the north this week, ISIS forces surrounded Iraq's largest oil refinery, a portion seen here in Satellite images burning.
If it's overtaken, the militants would gain control over a significant portion of Iraq's gas and power supply.
And Iraq's security forces have little ability to regain control of all that has been lost. They have no offensive capability and no real air power.
And now a growing fear, more westerners joining the ranks of foreign fighters descending on the country.
UNIDENTIFIED MALE: We will go to Iraq in a few days, and we will fight them.
RADDATZ: This flashy new propaganda video showing British and Australian recruits.
In response to the terror group's march, young Iraqi men are scrambling through Baghdad's marketplaces to fight body armor and uniforms left behind by the American military, vowing to defend their city.
UNIDENTIFIED MALE: I have to fight for my family, for my country, for everything.
RADDATZ: And if they can't find uniforms, they go anyway. We saw thousands and thousands of young Shia men, no training, no weapons lining up to serve.
The men have all just shown up spontaneously. They are anywhere from about 12-years-old and up, some have already lost family members to the jihadi fighters.
And behind this battle, everyday citizens who have already been through so much. This family moved to Syria during the worst parts of the war in Iraq, now with war raging in Syria they are back.
11-year-old Iba (ph) and the other children all have the same nightmares.
What do you worry about most?
"The explosions," she said, "the explosions."
