The Kurdish-language Hawar news reported that the Kurdish fighters destroyed a key position of the Turkish troops and Ankara-backed militants near al-Vilat street in Afrin's center, killing four militants and wounding two more.
The Turkish military said in a statement last week that a total number of 3,820 Kurdish militants have been killed of held captive since the start of Operation Olive Branch in Syria's Afrin region.
The General Staff of the Turkish Armed Forces said 52 Turkish soldiers were killed while 229 others wounded since the beginning of the Afrin operation.
Turkey launched Operation Olive Branch on Jan. 20 to clear the Kurdish militants from Afrin in Northwestern Syria.
On March 18, Turkish-backed troops captured the town of Afrin, which had been a major hideout for the PYD/PKK since 2012.
The army said at least 90 militants were killed or held captive in Turkey's Eastern Bitlis and Bingol, and Southeastern Diyarbakr and Mardin provinces, and in Northern Iraq from March 24-30.
The military added that the Turkish forces also seized a large amount of ammunition, including rifles, rocket projectors, grenades, ammonium nitrate and C-4 explosive, during the operations.
