Infighting between two militant groups in Syria’s divided city of Aleppo has left at least 25 terrorists from both sides dead and injured.

The clashes erupted in the city’s militant-held eastern region between the Fastaqim Union and Nour al-Din al-Zenki Movement groups.

The fighting broke out after al-Zenki militants attacked regions held by the rival terrorist group after it arrested the al-Zenki’s commander.
