"An ISIL suicide attacker stormed a bus carrying tens of militants trying to enter the Turkish territories via Adena border crossing, killing at least 35 fighters," Hesam al-Idlibi said, adding, "The militants in the bus were to move toward Jarabulus in Northern Syria via Turkish land."

"Chairman of Aleppo's Supreme Council of Judges Sheikh Khalid al-Seyed, Shadow Deputy Governor of Aleppo Mohammad al-Faraj and Hosham al-Khalifeh, a commanaer of Ahrar al-Sham were among the killed militants in Adena attack.

Most of the killed militants were the members of Ahrar al-Sham, Faylaq al-Sham and al-Shamiyeh Front.

Southern Idlib was the scene of fierce clashes between Ahrar al-Sham and Jund al-Aqsa on Friday, and scores of militants from both sides were killed or wounded in the clashes.

"Ahrar al-Sham fighters arrested a number of Jund al-Aqsa near Saraqib and stormed the house of Ali al-Issa, one of the commanders of Ahrar al-Sham, that resulted in the escalation of infighting among the rival terrorist groups," sources said.

"In Khan Sheikhoun, Jund al-Aqsa captured Ahrar al-Sham positions and then the town," they added.

In the meantime, Syrian fighter jets bombed heavily a base of the terrorists in the Eastern side of al-Dana, leaving scores of militants dead.
