Abu Thabat, a Free Syrian Army official, said his group has received reinforcements from two other battalions in the fight in what's been rebel-controlled territory. They've managed to push the al Qaeda-linked fighters back some, though the battle continues.
"We are regrouping," Thabat said. "We will call for more reinforcements and will probably attack tonight."
A short time later, though, a scanned letter signed by an Islamic State of Iraq and Syria member, a captain in the Free Syria Army and two witnesses appeared to indicate that these hostilities were over -- at least for now.
According to the letter posted on the Facebook page for a rebel-held border crossing community, the parties have agreed to an immediate cease-fire, the prompt return of prisoners and seized property and the formation of a committee to look at resolving the two sides' dispute long-term.
