Not just them either.....al Nusra and AQ as well. Plus now AQ vs AQ.
The Qatar-based Al-Jazeera TV reported that al-Qaida leader Ayman al-Zawahri urged leaders of the Iraqi al-Qaida branch and the Nusra Front in Syria to end their disagreements and "stop any verbal or actual attacks against one another."
Al-Zawahri's call could also reflect a bid to carve out a more significant role for al-Qaida in the Syria civil war. Jabhat al-Nusra, or the Nusra Front, is the most powerful rebel force fighting to topple President Bashar Assad.
In April, al-Qaida in Iraq said it had joined forces with the Nusra Front, forming a new alliance called the Islamic State in Iraq and the Levant.
In Sunday's letter, al-Zawahri chastises the head of al-Qaida in Iraq, Abu Bakr al-Baghdadi, saying he announced the merger without consulting al-Qaida's leadership. He also admonished al-Golani for publicly distancing himself from the merger.
"The Islamic State in Iraq and the Levant will be abolished," al-Zawahri said, adding that Nusra Front will remain an independent branch of al-Qaida. Al-Baghdadi and al-Golani are to stay on as leaders of their respective branches for another year, after which the al-Qaida leadership will decide whether they will keep their posts or be replaced
The merger had also caused friction among rebels on the battlefield who feared the announcement would further discourage Western powers discussing funneling weapons, training and aid toward rebel groups and army defectors.....snip~

Al-Qaida's Iraq head defies boss over Syria fight.....
The leader of al-Qaida's Iraq arm defiantly rejected an order from the terror network's central command to stop claiming control over the organization's Syria affiliate, according to a message purportedly from him that was posted online Saturday.
"The Islamic State in Iraq and the Levant will continue," al-Baghdadi said. "We will not compromise and we will not give up."
Al-Baghdadi is now defying that command. In his statement, he referred to "the letter attributed to Sheik al-Zawahiri," suggesting he was calling into question the authenticity of the letter. "
I chose the command of God over the command that runs against it in the letter," al-Baghdadi said.....snip~

IMO.....the FSA couldn't stop weapons from falling into the hands of AQ or others, ever!
