BEIRUT -Clashes in Syria’s northeast between regime troops and forces aligned with the Kurdish-led Syrian Democratic Forces killed two from each side on Wednesday, a war monitor said. Syria’s Kurds set up a semi-autonomous administration in the country’s northeast in 2013 after government troops withdrew. The SDF, a key US partner in fighting the Islamic State jihadist group, is the Kurdish administration’s de-facto army. Clashes between Kurdish and regime forces are rare in the region.  “Two regime soldiers were killed and others were wounded” while two members of an SDF-affiliated “military council” in Tal Tamr died after an “armed clash” in the area, the Syrian Observatory for Human Rights said.
