BEIRUT (Reuters) - An al Qaeda affiliate in Syria battled rival rebels across the country's north on Saturday and dozens of bodies piled up in a hospital in an insurgent-held city, a monitoring group said.

A week of infighting between the al Qaeda-linked group, the Islamic State of Iraq and the Levant (ISIL), and other groups including another al Qaeda-affiliated faction has killed hundreds of fighters opposed to President Bashar al-Assad.
