More U.S. Arms Flow to ISIS

The Telegraph reports:

Two of the main rebel groups receiving weapons from the United States to fight both the regime and jihadist groups in Syria have surrendered to al-Qaeda. 

The US and its allies were relying on Harakat Hazm and the Syrian Revolutionary Front to become part of a ground force that would attack the Islamic State of Iraq and the Levant (Isil). 

For the last six months the Hazm movement, and the SRF through them, had been receiving heavy weapons from the US-led coalition, including GRAD rockets and TOW anti-tank missiles. 

But on Saturday night Harakat Hazm surrendered military bases and weapons supplies to Jabhat al-Nusra, when the al-Qaeda affiliate in Syria stormed villages they controlled in northern Idlib province.

...  For the United States, the weapons they supplied falling into the hands of al-Qaeda is a realisation of a nightmare. 

It was not immediately clear if American TOW missiles were among the stockpile surrendered to Jabhat al-Nusra on Saturday. However several Jabhat al-Nusra members on Twitter announced triumphantly that they were.

 (Underline mine). Yet another reason why it is stupid to fight via proxies.
