DAMASCUS — The head of Syria's jihadist Al-Nusra Front pledged allegiance to Al-Qaeda chief Ayman al-Zawahiri on Wednesday, but distanced his group from claims it had merged with Al-Qaeda in Iraq.

The announcement is likely to bolster assertions by the regime of Syrian President Bashar al-Assad that it is fighting "terrorists" who want to impose an Islamic state, and could further complicate Western attempts to help rebel forces.

"The sons of Al-Nusra Front pledge allegiance to Sheikh Ayman al-Zawahiri," Abu Mohammed al-Jawlani said in the recording.

But, he added, "we were not consulted" on an announcement by Al-Qaeda in Iraq chief Abu Bakr al-Baghdadi on Tuesday of a merger with Al-Nusra Front.

"We inform you that neither the Al-Nusra command nor its consultative council, nor its general manager were aware of this announcement. It reached them via the media and if the speech is authentic, we were not consulted," Jawlani said.

He added that the group would not be changing its flag or its "behaviour".

"Al-Nusra Front will not change its flag, though we will continue to be proud of the flag of the Islamic State of Iraq, of those who carry it and those who sacrifice themselves and shed their blood for it," said Jawlani, acknowledging he had fought in Iraq alongside the ISI, Al-Qaeda's Iraqi branch.

"We reassure our brothers in Syria that Al-Nusra Front's behaviour will remain faithful to the image you have come to know, and that our allegiance (to Al-Qaeda) will not affect our politics in any way," he added, keen to assert the group's autonomy.

Jawlani's comments came a day after the ISI made a surprise announcement that Al-Nusra was part of its network, confirming long-held suspicions that led the United States to put the Syrian jihadist group on its terror blacklist.

"It is time to declare to the Levant and to the world that the Al-Nusra Front is simply a branch of the Islamic State of Iraq," ISI chief Baghdadi said in an audio message.
