Syrian rebels clash with Kurds in northeast - activists

BEIRUT (Reuters) - At least 56 people have been killed in a week of fighting in northeast Syria between anti-government rebels and members of the long-oppressed Kurdish minority who have seized on the civil war to try to secure self-rule, activists said on Tuesday.

The British-based Syrian Observatory for Human Rights, which collates reports on Syria's violence from local activists, said on Tuesday that the anti-Damascus rebels were using tanks and mortars on Tuesday against Kurdish forces.
