|ISIS Terrorists Posing For Pictures In Syria|
Unidentified gunmen attacked Islamic State militants in the eastern Syrian town of al-Mayadin overnight, killing more than 12, the latest in a series of guerrilla attacks on the ultra-hardline group in areas it controls near the Iraqi border.
The attacks in Deir al-Zor province were carried out by two separate groups of gunmen, the Syrian Observatory for Human Rights reported. Islamic State, which seized nearly all of Deir al-Zor province last year, has faced a wave of hit-and-run attacks by unidentified gunmen in the area.
There was no immediate claim of responsibility for the attacks. Syrian state media attributed similar attacks in January to "popular resistance" to Islamic State, which has brutally suppressed any opposition to its control.
The first group of assailants opened fire on an Islamic State patrol, killing 12 gunmen, before attacking Islamic State members who were guarding a courthouse. They were riding at least two motor bikes.
A second group of gunmen meanwhile attacked an Islamic State checkpoint in the same town, killing and injuring an unknown number of the Islamic State militants, the Observatory reported.
Al-Mayadin is located about 60 km (40 miles) from the border with Iraq.
While it has lost control of most of Deir al-Zor province to Islamic State, the Syrian government still controls part of the Deir al-Zor city.
