Israel will not take action against Russian fighter jets that encroach into its air space, a senior air force official said on Thursday. The issue of Russian sorties in Syria was magnified in recent days after Turkey downed a Su-24 fighter jet that it claims entered its air space near the border. According to Israeli military officials, such a scenario is not in danger of repeating itself in the skies over the Golan Heights. 'The Russian military is a new, key player which we are not ignoring,' a senior military official told reporters on Thursday. 'There is a clear boundary here, and they are busy with their matters, and we are busy with ours.'
