Two killed as Syrian troops open fire at Turkish border

Turkey has protested after Syrian forces opened fire across the border, in the first such attack since Turkey began housing refugees from the unrest.

Ankara summoned Syria's envoy after two incidents in which violence spilled over into Turkey, leaving at least two people dead and many injured.

Separately, a Lebanese cameraman was shot dead on the Syria-Lebanon border.

The violence comes amid fading hopes that a UN-brokered Syria ceasefire will start on Tuesday as planned.
