In this photo released by the Syrian official news agency SANA, Syrian troops deploy in the northern town of Tal Tamr, Monday, Oct 14, 2019. The move toward Tal Tamr came a day after Syria's Kurds said Syrian government forces agreed to help them fend off Turkey's invasion - a major shift in alliances that came after President Donald Trump ordered all U.S. troops withdrawn from the northern border area amid the rapidly deepening chaos.
