From Reuters:
American forces were involved in their first ground battle with Islamic State fighters, according to Kurdish media outlet Shafaq News, near the Ain Al-Assad base in the Anbar province of Iraq early Sunday. The report could not be independently verified.
For now:
The Pentagon has not released information on any American involvement in ground fighting with Islamic State.
And:
Since announcing US-led-coalition airstrikes against Islamic State in August, US President Barack Obama has repeatedly stated that he would not commit troops to another ground war in Iraq. Yet the Pentagon’s top brass have since said that the option remains on the table.
