Israel's PM says it will "not allow any threat" to the minority in Syria after sectarian clashes in which dozens were killed.

Israel struck a target near the presidential palace in the Syrian capital after the Druze community in both countries called for help following a series of violent clashes between the minority group and Syrian government forces.

Sectarian violence has erupted again in Syria, raising fresh doubt on the ability of the new Islamist rulers to control armed factions and calm tensions.
