Militants from the Islamic State of Iraq and the Levant (ISIL) executed at least 22 people, including 12 other opposition groups' militants, in the north of the country Tuesday, a monitoring group said.

"ISIL members executed at least 22 persons with firearms or knives, after taking control of Shuyukh outside the town of Jarabulus" in Aleppo province, the opposing UK-based Syrian Observatory for Human Rights, told AFP.

Among those killed were at least 12 armed terrorists, he mentioned.

ISIL seized Jarabulus, near the northern border with Turkey, from the terrorists of the other opposition groups last month.
