Israel shot down a Syrian drone that penetrated its airspace on Wednesday, Prime Minister Benjamin Netanyahu said, highlighting an escalation of volatility near the frontier that Netanyahu discussed in Moscow with Damascus¡¯s biggest ally.

¡°A drone penetrated from Syria¡¯s territory to Israel¡¯s territory several hours ago. It was successfully shot down. And I would like to point out that we will be preventing any attempts to violate our air or land border,¡± Netanyahu said on Wednesday as he met President Vladimir Putin.

It was the second time in less than three weeks Israel says it fired a Patriot missile at a drone that flew across the frontier. Tension has increased at the border as President Bashar Assad¡¯s forces have pressed toward it with an assault against rebels.
