BEIRUT — Traffic returned to a major highway in northeastern Syria for the first time in seven months on Monday, following Russian mediation to reopen parts of the road captured last year by Turkey-backed opposition fighters.

Syrian Kurdish media and a Syrian Kurdish official said several vehicles accompanied by Russian troops began driving in the morning between the northern towns of Ein Issa and Tal Tamr. The two towns are controlled by government forces and Syrian Kurdish fighters while the area between them is mostly held by Turkey-backed opposition fighters.

Turkish troops and allied Syrian fighters captured parts of the highway known as M4 in October, when Ankara invaded northeastern Syria to drive away Syrian Kurdish fighters. The M4 links Syria's coastal region all the way east to the Iraqi border.

Four convoys will drive on the M4 every day with two leaving from Tal Tamr and two from Ein Issa, according to the Kurdish ANHA news agency. The report said a convoy will leave from each town at 8 a.m., and another set of convoys will do the same, three hours later.

The ANHA agency added that the opening of the highway will shorten the trip between the two towns as people previously had to take roundabout, side roads.

"This is the first time the road has been opened" since October, said Mervan Qamishlo, a spokesman for the Kurdish-led and U.S.-backed Syrian Democratic Forces.

Russia, a main power broker with Turkey in Syria, mediated the deal to reopen the highway, he said. Russia and Turkey back rival groups in Syria's nine-year conflict.
