Beirut: Syrian opposition activists and state media say an explosion has targeted an office of the Al Qaeda affiliate in northern Syria, inflicting casualties.
Syrian state TV did not provide further details in its report. The Britain-based Syrian Observatory for Human Rights says the explosion occurred near the office belonging to the Al Qaeda-linked Levant Liberation Committee on Friday.
The Observatory says two of the militant group's fighters were killed and several others were wounded.
The Ibaa news agency, which is linked to Al Qaeda, says the blast in the village of Urum al-Kubra, west of the northern city of Aleppo, left "several martyrs" and wounded people.
The explosion comes amid rising tension in northern Syria between the Al Qaeda-linked group and other factions, including more moderate rebels.
