AKCAKALE, Turkey (AP) — Turkey's official news agency says Turkey-backed Syrian opposition forces have reached a strategic highway in northeastern Syria as Turkey's offensive against Syrian Kurdish fighters enters its fourth day.

Anadolu news agency said Saturday the forces have arrived at the M-4 highway that connects the Syrian towns of Manbij and Qamishli. The road is about 30 kilometers (19 miles) south of the Turkish border.

Turkey has said it aims to push back Syrian Kurdish People's Protection Units, or YPG, which it considers terrorists for its links to a decades-long Kurdish insurgency within its own borders.

Erdogan said Friday Turkey won't stop until the YPG, who forms the backbone of the U.S.-backed ground force against the Islamic State, withdraws below a 32 kilometer (20 miles) deep line.
