Islamist rebel groups in the Syrian city of Aleppo have rejected the new Western-backed opposition coalition that was formed in Qatar on 11 November.
In an internet video, they denounced the National Coalition for Syrian Revolutionary and Opposition Forces as a conspiracy, the BBC reports.
Calling themselves the representatives of the fighting formations in Aleppo, they say they intended to establish an Islamist state in Syria once President Bashar al-Assad is removed from power.
The European Union recognised the new coalition on Monday as "legitimate representatives of the Syrian people, but did not grant it full recognition.
France has already backed the group as "sole representative" of Syrians.
It has also been given full recognition by Turkey and the six Gulf states.
The United Kingdom may also follow suit, with Foreign Secretary William Hague due to make a parliamentary statement later on Tuesday, reports the BBC.
