Syrian army supported by Lebanese Hezbollah group is closing in on the ISIS bastion city of al-Bab in northern Syria.
Separately, Turkish forces and allied rebels are advancing in the northern part near the Turkish borders.
According to a monitor group report on Thursday, the intense battles are raging between Syrian army and Hezbollah on one side with the backing of Russian artillery shelling, against the IS in the southern and southwestern part of the city of al-Bab.
Al-Bab is the last major ISIS bastion in the northern province of Aleppo, near the Turkish frontier, said the Syrian Observatory for Human Rights.
As for the Turkish forces, the troops are aiming to divert the attention of the IS militants inside the city, by heavily shelling al-Bab by airstrikes and artillery shelling.
Meanwhile Turkish Operation Euphrates Shield continues to register successes against Daesh terrorist with hundreds being killed since the operation began in August last year.
