At least 100 Syrian soldiers and 30 rebels from the al-Qaeda affiliated group al-Nusra Front were killed in three days of fighting in a town near the Iraqi border taken by insurgents on Thursday, an opposition monitoring group said.

Coinciding with the report by the Syrian Observatory for Human Rights was a video posted on YouTube showing fighters from the Nusra Front celebrating and chanting "Allahu Akbar, Nusra Nusra".
