A senior rebel commander in Syria is reported to have been killed by rebels from a rival group linked to al-Qaeda.
Kamal Hamami, of the Free Syrian Army's (FSA) Supreme Military Council, was meeting members of the rival group "to discuss battle plans" when he was ambushed and shot.
An FSA spokesman said he was told by the Islamic State of Iraq and the Levant that they had killed Mr Hamami.
The killing is part of an escalating struggle within the armed uprising between moderates and Islamists, sparking fears of a war within the civil war.
