This is coolbert:

Escalating involvement, the invasion of Iraq by the forces of ISIL now creating a regional war, Iran, Syria and Iran all involved.

"Syrian war planes strike inside Iraq, sources say"

"Syria war planes struck two separate Islamic State of Iraq and Syria (ISIS) convoys near the town of Al Qaim just inside Iraq over the weekend, two well-placed senior U.S. defense officials told Fox News. The Syrian planes struck on Saturday with the help of Iranian intelligence, sources familiar with the incident said."

Sunni versus Shia no-holds-barred and no-quarter combat!
